Replacement Filters — Austin Air, Echo Water & Tyent from $29 to $3,500
Peak Primal Wellness carries replacement filters from Austin Air Systems, Echo Water, and Tyent, covering everything from basic pre-filters at $29 to the ECHO One Ultra Pure Hydrogen Water System at $3,500. Whether you need an air filter replacement for a whole-home purifier or a water filter replacement for a hydrogen-enriched drinking system, the right filter keeps your equipment performing as intended.
These products are for people who already own a purifier or water system and want to maintain its effectiveness without guessing at compatibility. Filters are not all interchangeable, so the main decision is matching the replacement to your exact model, then deciding how much filtration capacity you actually need for your space or household size.

Filters Buying Guide: Three Decisions
Answer these in order and the shortlist writes itself.
Match the Filter to Your Existing Machine
Model Compatibility: Austin Air replacement filters are not universal. Full-size machines and Junior-series units use different filter dimensions, so confirm your purifier's model number before selecting.
Water System Fit: The ECHO One is a complete system rather than a drop-in filter, so purchasing it means replacing your current water setup rather than servicing an existing one.
Size the Filter for Your Room or Household
Small Spaces: Junior-series filters like the $295 HealthMate Junior or the $320 Allergy Machine Junior are built for compact rooms. Pairing a standard-series filter with a Junior machine is not compatible.
Larger Rooms: Full-size filters like the $395 HM400 and $445 HM450 are designed for the standard Austin Air machines and cover more square footage per air change cycle.
Household Load: Homes with pets or multiple occupants go through pre-filters faster. Budget for more frequent pre-filter swaps at $29 to $34 alongside your standard main-filter replacement schedule.
Decide on Your Primary Filtration Goal
Particles and Allergens: A HEPA filter is the core tool for dust, pollen, dander, and mold spores. Most Austin Air main filters include true HEPA media as their central filtration stage.
Gases and Chemicals: If VOCs, formaldehyde, or smoke are the concern, step up to the HealthMate Plus line. The added activated carbon blend handles gas-phase contaminants that HEPA alone cannot trap.
Water Quality: For drinking water, the ECHO One targets dissolved impurities and adds molecular hydrogen rather than just removing sediment, which is a fundamentally different approach from air purifier filters.
Key Benefits of Filters
Sustained Air Quality Over Time
A fresh air filter replacement restores your purifier to its original performance level, which degrades gradually as the media loads with captured particles. Austin Air filters are rated for up to five years, so a single replacement covers a long maintenance window rather than requiring annual swaps.
Reduced Allergen and Asthma Triggers
Replacement filters in the Austin Air Allergy Machine line are specifically engineered to capture the fine particles most likely to irritate airways, including pollen, dust mite debris, and pet dander. Keeping the filter fresh means those allergens are actually being removed from the air rather than passing through a saturated medium.
Cleaner, Hydrogen-Enriched Hydration
The ECHO One water filter system goes beyond standard filtration by infusing water with molecular hydrogen, which is a distinct category from conventional purifier filters. For people who prioritize hydration as part of a recovery or wellness routine, this represents a meaningful upgrade over tap or basic filtered water.
Odor and Dander Control for Pet Owners
The Austin Air Pet Machine Filter combines HEPA particle capture with activated carbon media that specifically targets pet odors, which standard replacement filters in non-pet configurations do not address as directly. Replacing it on schedule keeps the carbon layer from becoming saturated and losing its odor-absorption capacity.

Filtration Stages in Core Austin Air Models
Most flagship Austin Air replacement filters use a four-stage system that layers pre-filtration, HEPA media, and activated carbon to address particles and gases in a single pass. This multi-stage approach is what separates them from single-medium purifier filters.
Rated Lifespan on Main Austin Air Filters
Austin Air designs its main filter media to last up to five years under typical residential conditions, which is a longer replacement cycle than most competing air filter replacement products on the market. Pre-filters are the exception and need more frequent attention.
Particle Capture Rate at 0.3 Microns
True HEPA filter certification requires capturing at least 99.97% of particles at the 0.3-micron threshold, which is the hardest particle size to trap and the standard Austin Air uses across its HEPA-rated filter lineup. This figure is verified by the filter media, not the housing or fan.
Ownership: Warranty, Care and Returns
Warranty & Support
Austin Air backs its replacement filters with a five-year pro-rated warranty covering defects in materials and filtration media under normal use conditions. The ECHO One and other water products carry their own manufacturer warranty terms, which vary by product and should be confirmed at the time of purchase. Warranty coverage applies to the filter itself and does not extend to the purifier housing or external components.
Care & Cleaning
Pre-filters like the Standard Pre-Filter and Junior Pre-Filter can be vacuumed gently to remove surface debris between replacements, which extends their useful life without compromising the main media. Main HEPA and carbon filters should not be washed or exposed to moisture, as water damages the filtration media and voids the warranty. Store unused replacement filters in their original sealed packaging in a dry location away from direct sunlight.
Returns
Unused replacement filters in their original, unopened packaging are eligible for return within 30 days of the purchase date. Once a filter has been installed or removed from its sealed packaging, it cannot be returned due to hygiene and contamination concerns. If you received the wrong model or need to exchange for a different size, contact Peak Primal Wellness before opening the packaging to preserve your options.

Filters FAQ
What are the best replacement filters available at Peak Primal Wellness?⌄
For air purification, the Austin Air HealthMate Plus HM450 Filter at $445 is a strong all-around choice because it targets gases, VOCs, and formaldehyde in addition to particles. The Austin Air Allergy Machine Filter at $405 is better suited to asthma and allergy sufferers. For water, the ECHO One Ultra Pure Hydrogen Water System at $3,500 is the flagship option for hydrogen-enriched drinking water.
How do Austin Air Systems, Echo Water, and Tyent compare?⌄
Austin Air Systems focuses entirely on air purification, with a deep lineup of HEPA and activated carbon filters for different room sizes and sensitivities. Echo Water specializes in hydrogen water technology, targeting cellular hydration rather than air quality. Tyent rounds out the water category with ionization-based systems. Each brand occupies a distinct niche, so the comparison is really about which wellness goal you are addressing.
How often should I replace my Austin Air filter?⌄
Austin Air designs its main filters to last up to five years under normal residential use, which is longer than most competing purifier filters on the market. Pre-filters like the Standard Pre-Filter at $34 should be replaced more frequently, roughly every few months, depending on how much dust, hair, and pet dander your space generates. Checking the pre-filter monthly is a simple habit that protects the main filter.
Do I need a specific model filter for my Austin Air purifier?⌄
Yes. Austin Air replacement filters are model-specific and are not interchangeable between the full-size machines and the Junior-series units. The Junior line has its own smaller filters, like the $295 HealthMate Junior Filter, while the standard machines use larger media. Always confirm your purifier's model number before ordering to avoid a return.
What does a HEPA filter actually capture?⌄
A true HEPA filter captures at least 99.97% of airborne particles at 0.3 microns, which covers dust mite debris, mold spores, pollen, pet dander, and many bacteria. The echo water filter and Austin Air HEPA models are engineered to different standards since one targets air and the other targets dissolved impurities in water, so particle capture specs are not directly comparable across categories.
What is the ECHO One and what does it do?⌄
The echo water filter system in the ECHO One Ultra Pure Hydrogen Water System ($3,500) infuses drinking water with molecular hydrogen, a small antioxidant molecule that passes easily into cells. It is designed as a daily hydration upgrade rather than a standard filtration product, and it sits at the premium end of Peak Primal Wellness's filter catalog.
Is the Austin Air HealthMate Plus worth the upgrade over the standard HealthMate?⌄
If your concern is chemicals, smoke, or off-gassing from furniture and flooring, the HealthMate Plus HM450 Filter at $445 is worth it because it adds broad-spectrum gas adsorption that the standard HealthMate does not match. For straightforward dust and allergen removal in a typical home without chemical sensitivities, the $395 HM400 Replacement Filter does the job well at a lower price.
Can I use a replacement filter to address pet odors?⌄
The Austin Air Pet Machine Filter at $415 is specifically designed for that use case, combining a HEPA filter with activated carbon media that targets odors and dander simultaneously. The four-stage system handles both the particulate side (dander, hair) and the odor side, which is something a HEPA-only filter cannot accomplish on its own.
What is the difference between a pre-filter and a main filter?⌄
A pre-filter is the outer layer that captures large particles like hair, dust, and pet fur before they reach the denser main media. Replacing it regularly, starting with options like the $29 Junior Pre-Filter or the $34 Standard Pre-Filter, extends the life of the more expensive main filter significantly. The main filter does the fine-particle and gas removal work and is the costlier component to replace.
How do I know which filter is right for a small room versus a large space?⌄
Austin Air makes Junior-series filters for smaller spaces and standard-series filters for larger rooms. For example, the $295 HealthMate Junior Filter is sized for compact areas, while the $395 HealthMate HM400 Replacement Filter is designed for full-size machines covering bigger rooms. Matching the filter to the correct machine is the primary sizing decision since the machine itself determines coverage area.
Are there any installation costs to budget for when buying replacement filters?⌄
Air filter replacements like Austin Air models are designed for tool-free, DIY swaps inside the existing purifier housing. There are no installation costs to account for beyond the filter price itself. Water systems like the ECHO One may require connection to a water line, so plumbing complexity varies by setup and is worth confirming before purchase.
What is the return policy on replacement filters?⌄
Unused replacement filters in original condition are eligible for return within 30 days of purchase. Filters that have been installed or exposed to air or water flow cannot be returned for hygiene and safety reasons. If you ordered the wrong model, contact Peak Primal Wellness before opening the packaging to keep your return options intact.
