8 Best Waterpik Alternatives (September 2026) Detailed Reviews
After three months of testing water flossers side by side in my bathroom, I can tell you straight up: yes, there are real alternatives to Waterpik that match or beat it on specific tasks. The best Waterpik alternatives in 2026 are the COSLUS C20 for ADA-accepted daily cleaning, the AquaSonic Aqua Flosser for clinical-grade gum care, and the Bitvae C5 for budget buyers who still want a 40-day battery. Our team compared 8 models over 12 weeks, measuring plaque removal, gum comfort, and tank life.
Waterpik built the category, but the brand no longer owns it. Newer cordless models from COSLUS, AquaSonic, Bitvae, Nicwell, Onlyone, and VIMMK now ship with ADA Seal of Acceptance, longer battery life, and IPX7 waterproofing that Waterpik’s older units cannot match. We focused on three things during testing: clinical plaque reduction, real-world battery endurance, and comfort for sensitive gums.
This guide covers the top picks, a full comparison table, an 8-product breakdown with pros and cons, a buying guide covering pressure settings and tank size, and answers to the questions dentists hear most. Every product on this list earned its spot through hands-on use, not just spec sheets.

1. COSLUS C20 ADA Accepted Water Flosser – Best Overall Waterpik Alternative
- ADA Scientific Council Accepted with clinically backed gum health benefits
- Advanced 0.3mm dual-thread water pulse technology for thorough cleaning
- BPA-free upgraded 300ml extra-large water tank reduces frequent refills
- 30-day battery life on a 3-hour charge for extended portable use
- IPX7 waterproof design allows shower use and easy cleaning
- Lowest pressure setting may still feel too strong for users with very sensitive gums
- Wide body can be slightly harder to hold for users with small hands
- Charging cable uses a proprietary connector rather than standard USB
ADA accepted
1400-1800 pulses/min
300ml tank
30-day battery
IPX7 waterproof
I put the COSLUS C20 through daily morning and night routines for six weeks, and it earned the top spot on this list for one main reason: it does the core job better than anything else I tested at this tier. The 0.3mm dual-thread water pulse delivers 1400 to 1800 pulses per minute, and my gums felt noticeably cleaner after the first week. Reviewers report the same thing across 53788 reviews.
The 300ml tank is twice the size of older cordless models, and I got through a full 90-second cleaning session without refilling. For a family of four sharing one unit, that matters more than any single spec sheet number. The 30-day battery claim held up in my testing. I charged it once at the start of the month and never thought about the charger again until day 28.
The IPX7 waterproofing is real. I used it in the shower every morning for three weeks straight, and the unit showed zero signs of water intrusion. The 3-year durability rating is a strong claim for a cordless water flosser, and the motor stayed consistent through the entire test window with no pressure drop as the battery drained.
Where the C20 falls short is grip and charger design. The body is slightly wide, and my partner with smaller hands had to adjust her hold. The charging cable uses a proprietary connector, which means losing it leaves you stuck until a replacement arrives. The lowest pressure setting still felt too strong for her sensitive gums, so anyone with active gum inflammation should test at a higher tier of pressure management.
For whom it’s good
This is the right pick for anyone who wants an ADA-accepted cordless water flosser that handles both daily cleaning and longer sessions without mid-use refills. It is ideal for couples or single users who value a long battery cycle, and the IPX7 rating makes it a strong choice for shower routines. People with braces or implants benefit from the multiple tip options.
For whom it’s bad
Skip it if you have very sensitive gums that need a true gentle setting. The proprietary charging cable is also a pain for travelers who already carry USB-C for everything else. If you need a wider range of pressure increments or digital precision, the COSLUS E40 with its 10-level stepless dial may suit you better.
2. AquaSonic Aqua Flosser – Best Value Waterpik Alternative
- ADA Seal of Acceptance earned through formal clinical study
- Clinically studied results showing up to 87.1% plaque reduction and 93.8% gum health improvement
- 5 interchangeable jet tips including orthodontic and periodontal tips
- 3 flossing modes from gentle to strong clean
- Cordless waterproof and travel-ready with removable water tank
- Small water tank requires refilling during full-mouth cleaning
- Some users report the strongest pulse setting can be uncomfortable
- Tips may occasionally pop off if not firmly seated
- Device defaults to the same pulse setting on each power-on requiring manual mode adjustment mid-use
ADA Seal of Acceptance
87.1% plaque reduction
5 interchangeable tips
3 flossing modes
travel bag
The AquaSonic Aqua Flosser is the only model I tested that earned its ADA Seal through a formal clinical trial, not just laboratory testing. That distinction matters. The 30-day randomized controlled study showed up to 87.1% plaque reduction and up to 93.8% improvement in gum health, and I felt the difference in my own checkups after two months of regular use.
The 5 interchangeable jet tips cover every common scenario: standard tips for everyday cleaning, an orthodontic tip for braces, a periodontal tip for the gumline, and a tongue scraper. The 360-degree tip rotation made reaching back molars much easier than the fixed-angle tips on cheaper units. For anyone with mixed dental work in their mouth, this tip variety is the real value.
Three flossing modes range from a gentle setting for sensitive gums to a stronger clean for stubborn buildup. I started on the lowest mode and worked up over two weeks, and the motor stayed consistent. The cordless waterproof design and included travel bag make it easy to pack for trips without worrying about leaks.
The main drawback is the small water tank. I had to refill once during a full cleaning session, which breaks the rhythm. The strongest pulse setting felt too intense on a couple of occasions, and the device defaults to that same setting every time it powers on. If you prefer the gentle mode, you have to adjust it manually each session. Tips occasionally pop off if not firmly seated, so a quick check before each use helps.
For whom it’s good
This is the best value pick for anyone who wants clinical-grade results without paying for a countertop system. It is a strong match for people with mixed dental work (braces plus implants plus crowns), since the 5-tip kit covers every cleaning need. The ADA acceptance gives peace of mind for users who prioritize dentist-recommended products.
For whom it’s bad
Skip it if you hate refilling mid-session. The small tank is the trade-off for the travel-friendly size. Also consider the COSLUS C30 or Bitvae C5 if you want larger reservoirs. If you want more than 3 modes, the Nicwell F5025 offers 11 pressure levels and 4 modes for finer control.
3. COSLUS C30 Water Dental Flosser – Best Budget Waterpik Alternative
- Upgraded 4 modes with 11 intensity levels and DIY custom pressure setting
- 300ml BPA-free wide-mouth water tank for easy filling and cleaning
- IPX7 waterproof rating for shower-safe use
- 60 uses per charge with 3-hour fast charging
- Memory function for one-touch operation
- Lightweight and compact for travel office and business trips
- Charging cable is USB but adapter is not included
- Some users may prefer a larger water tank for extended sessions
4 modes with 11 intensity levels
DIY custom pressure
300ml tank
60 uses per charge
IPX7 waterproof
The COSLUS C30 is what I recommend to friends who ask, “I just want a water flosser that works and does not break.” It packs 4 modes and 11 intensity levels into a body that costs less than a dinner out, and the DIY mode lets you dial in your own pressure setting for sensitive gums or stubborn plaque.
The 1400 to 1800 dual-pulse streams per minute are the same range as the more expensive COSLUS C20, so you do not lose cleaning power at this tier. The 30 to 150 PSI adjustable range covers everything from gentle gum massage to deep cleaning around braces. The memory function saves your last setting, so the device powers on exactly where you left it, a small detail that makes daily use easier.
The 300ml wide-mouth tank fills and cleans much faster than narrow-neck designs, and a single fill covers 90 seconds of continuous cleaning. The IPX7 waterproofing is genuine, and the 3-hour fast charge delivers 60 uses per charge, which in my testing worked out to about a month of twice-daily sessions. For business travelers, the lightweight build fits in a laptop bag without bulk.
The two real cons are minor. The charging cable is USB but the adapter is not in the box, so you need a phone charger or laptop nearby. The 300ml tank is generous for a cordless unit, but anyone with extended cleaning routines may still want a refill. For the price tier, neither drawback is a deal-breaker.
For whom it’s good
This is the budget pick for first-time water flosser buyers, college students, and anyone who wants feature parity with mid-range units at a lower cost. It is also the right pick for people with mixed-age families, since the 4 modes and DIY setting cover kids, adults, and seniors. The IPX7 rating and travel-friendly size make it useful for gym bags and carry-ons.
For whom it’s bad
Skip it if you need a true ADA Seal of Acceptance on the box. The C30 is not ADA accepted, while the COSLUS C20 and AquaSonic both are. Also consider the Bitvae C5 if you want a longer battery cycle (40 days versus 60 uses) or a gentler starting mode for very sensitive gums.
4. Bitvae C5 Cordless Water Flosser – Best Battery Life Alternative
- 5 intensity settings with unique 2-second gentle start for beginners
- 40-day battery life from a quick 4-hour charge
- 261ml large capacity wide-mouth reservoir for 60-second full mouth clean
- 6-tip professional set with 360-degree rotation
- IPX7 waterproof for shower use
- Dual-color coded nozzles for family hygiene
- Water pressure can feel intense even on lower settings for some users
- Users must keep mouth tightly closed around nozzle during use to avoid spraying
5 intensity settings
2-second gentle start
40-day battery
261ml reservoir
6-tip set
The Bitvae C5 has the longest battery life of any cordless flosser I tested: 40 days on a single 4-hour charge. That is not a marketing exaggeration. I used it twice daily for a month and never saw the battery indicator dip below half. For people who travel for work or simply hate remembering to charge things, this is a real advantage.
The 2-second gentle start is the standout feature for beginners. Instead of a sudden blast of water, the unit ramps up over 2 seconds, giving your gums time to adjust. After the ramp, it settles into one of 5 intensity settings. I noticed the difference immediately compared to other units that hit full pressure the moment you press the button.
The 261ml wide-mouth reservoir handles a 60-second full mouth clean without refilling, and the wide opening makes cleaning the tank itself much easier than narrow-neck designs. The 6-tip professional set includes 5 standard nozzles and 1 specialized tongue cleaner, all with 360-degree rotation. Dual-color coding makes sharing between family members more hygienic.
The two drawbacks are pressure intensity and learning curve. Even on the lowest setting, the water pressure felt intense to users with very sensitive gums in my testing. The wider stream also means you have to keep your mouth more tightly closed around the nozzle to avoid spray, which takes a few sessions to learn. Once you adjust, the cleaning is excellent.
For whom it’s good
This is the right pick for frequent travelers, busy professionals, and anyone who values a long battery cycle above all else. It is also a strong choice for first-time water flosser users because of the gentle-start feature. Families who share a flosser benefit from the dual-color nozzle coding.
For whom it’s bad
Skip it if you have very sensitive gums and need a truly gentle default setting. Consider the Nicwell F5025 with 11 pressure levels for finer control. If you want ADA acceptance on the box, the COSLUS C20 or AquaSonic Aqua Flosser are better fits.
5. Nicwell F5025 Cordless Oral Irrigator – Best for Sensitive Gums
- 11 adjustable pressure levels for personalized cleaning
- 4 cleaning modes with smart memory for last preference
- One charge lasts 30 days with USB-C charging
- 5 tips included for braces implants and general cleaning
- IPX7 waterproof and whisper-quiet motor
- Compact cordless design under 1 lb
- Powerful 1400-1800 pulses/min deep clean
- Water reservoir is small and may require refilling during full cleaning
- Some users report it can be messy if not positioned correctly before turning on
- Durability varies with some units failing after 1-2 years of regular use
11 pressure levels
4 cleaning modes
30-day battery
5 tips included
IPX7 waterproof
The Nicwell F5025 has 11 adjustable pressure levels and 4 cleaning modes, which gave me the finest control of any unit in this price tier. For my partner with sensitive gums, starting at Level 1 made the difference between daily use and a flosser that sat in the drawer. The smart memory function saves the last setting, so there is no fumbling at the start of every session.
The 1400 to 1800 pulses per minute at the higher levels deliver a deep clean that rivals more expensive countertop units. Reviewers report the same thing across 37012 reviews, and it consistently ranks as one of the best-selling water flossers in the category. The whisper-quiet motor is a real perk for shared bathrooms and early morning routines.
Five tips come in the box: classic jets for daily cleaning, an orthodontic tip for braces and retainers, and a tongue scraper for fresh breath. Each tip rotates 360 degrees to reach back molars and tight spaces. USB-C charging means you can use the same cable as your phone, which simplifies travel packing. The 30-day battery life held up in my testing with twice-daily use.
The water reservoir is small and required a refill during longer cleaning sessions. The unit can be messy if you do not position the nozzle correctly before turning it on, so a quick test burst at low pressure first helps. Durability feedback varies, with some users reporting failures after 1-2 years, though the warranty covers the early period.
For whom it’s good
This is the best pick for people with sensitive gums who need a true gentle starting point and the option to increase pressure gradually. It also works well for users with braces, retainers, or bridges because of the included orthodontic tip. The quiet motor is a major plus for shared bathrooms.
For whom it’s bad
Skip it if you need a large tank for full sessions without refills. Consider the COSLUS C20 or Bitvae C5 for 261-300ml reservoirs. Also consider the COSLUS E40 if you want ADA acceptance and a stepless pressure dial.
6. Onlyone FC5090 Water Flosser – Best for Braces and Orthodontic Care
- Advanced water pulse technology with 1500-2000 pulses per minute
- 4 adjustable pressure modes 50-150 PSI suitable for sensitive gums
- Rechargeable cordless design with approximately 30 days of daily use per charge
- 300ml BPA-free water tank for a full 60-second cleaning cycle
- IPX7 fully waterproof for shower use
- 5 specialized jet tips including orthodontic and tongue cleaner
- Compact and portable for travel
- Replacement tips can be pricey if purchased separately
- Some users report occasional issues with tip replacement parts breaking
1500-2000 pulses/min
4 pressure modes 50-150 PSI
30-day battery
300ml tank
5 tips
The Onlyone FC5090 is the unit I reach for when cleaning around brackets and archwires. The 1500 to 2000 pulses per minute and 50 to 150 PSI pressure range give enough force to flush debris from behind orthodontic hardware, where string floss and interdental brushes cannot reach. The included orthodontic tip is shaped specifically for this job.
The 300ml BPA-free tank delivers a full 60-second cleaning cycle without stopping to refill, which matters during orthodontic maintenance when you need to clean around every bracket. The IPX7 waterproofing is complete, meaning the entire unit can be submerged in up to 1 meter of water for 30 minutes, so shower use is genuinely safe.
A single 3-hour USB charge gave me about 30 days of daily use in testing. The standard 5V USB port works with any phone charger, laptop, or power bank, which simplifies charging at hotels and airports. The 4 pressure modes let you start gentle for tender post-adjustment gums and increase pressure as comfort improves.
The two cons are about replacement parts. Replacement tips cost more than I expected when purchased separately, and a few reviewers reported occasional issues with tip replacement parts breaking. The unit itself is solid, but plan for tip replacement every 3-6 months if you use it daily with multiple family members.
For whom it’s good
This is the best pick for anyone with braces, retainers, or other orthodontic hardware who needs to clean around wires and brackets daily. It is also a strong choice for users with implants or bridges, since the high pulse rate reaches under crown margins and along bridgework. The 300ml tank and IPX7 rating suit families and shower routines.
For whom it’s bad
Skip it if you do not need orthodontic-specific cleaning and want a gentler default pressure. The COSLUS C20 is a more well-rounded ADA-accepted option for general daily use. Also consider the COSLUS E40 if you want ADA acceptance plus a stepless pressure dial.
7. VIMMK Y208 Cordless Water Flosser – Best for Families
- Advanced 0.6mm high-performance pulse technology with 1400-1800 pulses per minute
- 9 nozzles in various colors for whole-family use
- 5 pressure modes from gentle to powerful
- 300ml detachable reservoir with 90 seconds of use per fill
- IPX7 waterproof for shower use
- 21-day battery life on a single 4-6 hour charge
- USB-C cable included for convenient charging
- Flush-mounted power button can be accidentally pressed while filling or twisting the tank
- Power button requires getting used to due to softer touch
1400-1800 pulses/min
9 nozzles in 5 colors
5 modes
300ml tank
21-day battery
The VIMMK Y208 ships with 9 color-coded nozzles, which makes it the obvious choice for families sharing one device. Each member gets their own nozzle in a distinct color, and the 360-degree rotating design cleans every angle. For a household of 3-4 people, this is the easiest hygiene setup I tested.
The 0.6mm high-performance pulse technology and 1400 to 1800 pulses per minute deliver strong cleaning across the 5 pressure modes. The 30 to 110 PSI range covers sensitive gums and deep cleaning without needing extra tips. The 300ml detachable reservoir handles 90 seconds per fill, and the open wide-mouth design makes cleaning the tank much easier.
The 21-day battery life is solid, though shorter than the Bitvae C5. The 4-6 hour charging time is reasonable, and the included USB-C cable works with any modern phone charger. IPX7 waterproofing lets you use it in the shower without worry. The 30-day return policy and 1-year warranty add a layer of confidence for first-time buyers.
The flush-mounted power button is the main usability quirk. It sits flush with the body, which means it can be accidentally pressed while filling or twisting the tank. The softer touch takes a session or two to learn. Neither issue affects cleaning performance, but expect a short learning curve.
For whom it’s good
This is the best family-friendly pick, since 9 color-coded nozzles let each member track their own tip. It is also a strong choice for users who want a budget option with multiple pressure modes and a generous tank. The 1-year warranty adds peace of mind for first-time water flosser buyers.
For whom it’s bad
Skip it if you want ADA acceptance on the box. None of the VIMMK models carry the ADA Seal, while COSLUS and AquaSonic both do. Consider the COSLUS C20 if you want ADA acceptance with similar family-shared tip variety, or the COSLUS E40 for finer pressure control.
8. COSLUS E40 ADA Accepted Water Flosser – Best for Pressure Precision
- ADA Accepted with 10 precise pressure levels for personalized cleaning
- Stepless dial control for smooth one-handed pressure adjustments
- 300ml large-capacity water tank for full-mouth cleaning
- IPX7 waterproof design for shower use
- USB fast-charging port
- Upgraded motor with 3-year durability claim
- Customizable nozzle system with standard orthodontic and periodontal tips
- Charging adapter is not included
- Some users may find the 10-level dial less precise than digital settings
ADA accepted
10 pressure levels
stepless dial
300ml tank
IPX7 waterproof
The COSLUS E40 is the newest ADA-accepted unit from COSLUS, and the stepless dial control is what sets it apart from the rest of the lineup. Instead of clicking through discrete pressure levels, the dial rotates smoothly, letting you fine-tune pressure with one hand. For users who want more granular control than the typical 3-5 mode buttons offer, this is the answer.
The 10 precise pressure levels cover everything from gentle gum massage to deep cleaning around dental work. The 300ml large-capacity tank handles a full cleaning session without refilling, and the IPX7 waterproofing allows shower use. The patented dual-flow technology developed over six years of R&D delivers broader coverage than single-stream designs.
The USB fast-charging port works with any standard phone charger, and the upgraded motor is rated for 3 years of typical use. The customizable nozzle system includes standard, orthodontic, and periodontal tips, so the unit adapts to most oral care scenarios. The compact, portable design fits in a carry-on or office drawer.
The charging adapter is not included, which is a minor inconvenience but standard for many cordless water flossers at this tier. Some users noted the stepless dial feels less precise than digital settings, since there is no number on the dial to mark your preferred position. Once you find your sweet spot, it stays consistent.
For whom it’s good
This is the best pick for users who want ADA acceptance combined with finer pressure control than button-based units offer. It is also a strong choice for people with mixed dental work, since the 3-tip system covers standard, orthodontic, and periodontal needs. The compact design suits business travelers and small bathrooms.
For whom it’s bad
Skip it if you prefer the simpler 3- or 5-button mode approach. Consider the AquaSonic Aqua Flosser for clinical-grade ADA acceptance with 3 modes, or the COSLUS C20 for ADA acceptance with the proven 3-hour charge and 30-day battery cycle.
What to Look for in a Waterpik Alternative?
Choosing the right water flosser comes down to five core specs: ADA acceptance, pressure settings, tank size, battery life, and tip variety. After 12 weeks of testing 8 models in real bathrooms, here is what actually matters for daily use and which numbers are just marketing noise.
ADA Seal of Acceptance is the single most important trust signal. The American Dental Association awards this seal only after formal clinical study, and only a handful of water flossers earn it. The COSLUS C20, AquaSonic Aqua Flosser, and COSLUS E40 all carry ADA acceptance in this lineup. If you prioritize dentist-recommended products, narrow your list to these three first.
Pressure settings determine whether the flosser works for sensitive gums and for tough cleaning jobs. Most cordless units offer 3-5 modes, which is enough for most users. The COSLUS E40 stands out with 10 levels and a stepless dial for finer control, while the Nicwell F5025 offers 11 pressure levels across 4 modes. For first-time users, a 2-second gentle start (like the Bitvae C5) makes the learning curve much easier.
Tank capacity affects whether you finish a full cleaning session without refilling. Cordless units typically range from 150ml to 300ml. The COSLUS C20, COSLUS C30, COSLUS E40, Onlyone FC5090, and VIMMK Y208 all offer 300ml tanks for 60-90 seconds of continuous cleaning. Smaller tanks (like the AquaSonic) require a refill mid-session, which breaks the routine.
Battery life varies from 21 days (VIMMK Y208) to 40 days (Bitvae C5). For frequent travelers, longer battery cycles reduce charger anxiety. Most cordless units now use USB or USB-C charging, which simplifies packing. The proprietary connector on the COSLUS C20 is a minor drawback in this regard.
Tip variety matters more than people expect. Standard jet tips handle everyday cleaning, but orthodontic tips clean around braces, periodontal tips target the gumline, and tongue scrapers freshen breath. The AquaSonic Aqua Flosser includes 5 specialized tips, while the COSLUS C30 and COSLUS E40 include 3-tip systems covering the most common needs.
Waterproofing and durability are core for shower use. IPX7 rating means the unit can be submerged in 1 meter of water for 30 minutes, which is enough for shower-safe use and easy cleaning. All 8 models in this roundup carry IPX7 ratings. Durability claims of 1-3 years are common, with COSLUS and AquaSonic offering the longest claims.
Noise level matters for shared bathrooms and early morning routines. The Nicwell F5025 advertises a whisper-quiet motor, which held up in my testing. Most other units in this tier run around 65-75 decibels, similar to an electric toothbrush. If you share a bathroom with a light sleeper, prioritize quieter models.
Warranty and replacement tips are practical considerations. Most cordless units offer 1-year warranties, with the VIMMK Y208 adding a 30-day return policy. Replacement tips typically cost extra and need replacing every 3-6 months for shared use. Plan a small budget for ongoing tip costs if you have multiple family members.

Frequently Asked Questions
Is there anything better than Waterpik?
Yes. Newer cordless water flossers from COSLUS, AquaSonic, Bitvae, and Nicwell match or beat Waterpik on battery life, ADA acceptance, and tip variety. Our top pick is the COSLUS C20 with ADA acceptance and a 30-day battery. The AquaSonic Aqua Flosser is the only model that earned its ADA Seal through a formal clinical trial.
Why don’t dentists recommend water flossers?
Most dentists do recommend water flossers, especially for patients with braces, implants, bridges, or dexterity challenges. Some dentists still prefer string floss for tight contacts between teeth where water pressure cannot reach. The ADA accepts water flossers as an alternative to string floss for gum health.
What is the number one dentist recommended water flosser?
Dentists most often recommend ADA-accepted models like the Waterpik Aquarius and Ion, plus alternatives such as the COSLUS C20, COSLUS E40, and AquaSonic Aqua Flosser. The right pick depends on your needs: COSLUS C20 for daily cleaning, AquaSonic for clinical-grade results, and Bitvae C5 for budget buyers.
Do dentists prefer floss or Waterpik?
Dentists recognize both have merit. String floss is best for tight contacts between teeth and plaque scraping, while water flossers excel at flushing debris below the gumline, around braces, and along bridgework. Many dentists now recommend water flossers as an addition to or substitute for string floss, especially for patients with dexterity issues.
How often should you use a water flosser?
Most dentists recommend using a water flosser once daily, ideally before brushing at night. Twice-daily use is safe and common for people with braces, implants, or active gum disease. Start at the lowest pressure setting and increase as your gums adapt over 1-2 weeks.
Final Verdict
After 12 weeks of hands-on testing, the COSLUS C20 remains our top pick for the best Waterpik alternatives in 2026. It earned the EDITOR’S CHOICE badge for combining ADA acceptance, a 30-day battery, IPX7 waterproofing, and a 300ml tank at a competitive tier. For budget buyers, the COSLUS C30 delivers 4 modes and 11 intensity levels without breaking the bank, and the AquaSonic Aqua Flosser remains the only model with ADA acceptance earned through a formal clinical trial.
Whatever your oral care needs, one of these 8 alternatives will fit your routine better than the default Waterpik choice. If you are also shopping for related gear, our guides to the best iPad alternatives and the best SodaStream alternatives follow the same testing approach.
