LifeWell S20 Replacement Filters: What Fits and Where to Buy

Which replacement filters fit the LifeWell S20?

The correct set for the LifeWell S20 Atmospheric Water Generator is the LifeWell A10 / S20 Replacement Filter Set (PAC + UF + CB). It includes the three water-filtration stages used by the S20:

• PAC
• Ultrafiltration
• Carbon block

These cartridges are installed as three screw-in filter bottles in a single bay under the machine’s top cover. The set is made for the LifeWell S20, model LW-S20-AWGEN and SKU LWS20.

The S20 also uses a medium-efficiency air filter before the water stages. The replacement set described here is specifically named for the PAC, ultrafiltration and carbon block stages.

For current purchasing information, see the replacement filter sets hub. For a broader explanation of the cartridge format, read the A10 Atmospheric Water Generator Replacement Filters compatibility and buying guide.

A10-platform compatibility

The LifeWell S20 is built on the widely rebadged A10 countertop atmospheric water generator platform. Machines on this shared OEM platform use the same three screw-in water-filter bottles in one bay under the top cover, even when the exterior carries a different brand name.

The LifeWell A10 / S20 Replacement Filter Set fits the following listed machines:

• LifeWell S20
• Solaris Watergen A10
• Pure AirWater A10
• Aeraqua AERAQUA-10
• Forever Water A10, model FW-A10
• Unbranded A10-platform units sold under generic “make water from air” titles

Model-specific pages are available for the Solaris Watergen A10, Pure AirWater A10, Aeraqua AERAQUA-10, Forever Water A10 and unbranded A10-platform machines.

This fit guidance is based on the machines sharing the same OEM platform, not on a claim that LifeWell tested a competitor-branded machine. Free returns are available within 30 days. LifeWell is not affiliated with, endorsed by or sponsored by Solaris Watergen, Pure AirWater, Aeraqua or Forever Water.

Do not assume that a cartridge fits merely because a machine is described as an atmospheric water generator. Fit is stated only for the models and A10-platform units listed above.

Where to buy LifeWell S20 replacement filters

The LifeWell A10 / S20 Replacement Filter Set is offered for $129.95 as a one-time purchase. It is also available for $99.95 every six months on subscription.

The subscription interval matches the stated six-month replacement schedule. A one-time order may be more suitable for someone who prefers to manage replacement dates independently, while the subscription provides a recurring delivery schedule. The cartridges supplied are the same named PAC, ultrafiltration and carbon block set in either purchase option.

Before ordering for a machine with another badge, compare its exact model with the compatibility list. Owners of generic machines can also consult the guide to replacement filters for unbranded “make water from air” machines.

When to replace the filters

Replace the S20 water filters every six months or when the water-filter indicator lights, whichever provides the prompt. After replacement, hold the water-filter reset button for 2 seconds.

The indicator must be reset after the new cartridges are installed so the machine can begin a new filter interval. For more focused instructions, see How to Replace A10 AWG Filters and Reset the Filter Indicator and the LifeWell S20 filter replacement schedule.

Keeping the model name, replacement date and next scheduled change in a simple household maintenance record can make recurring service easier to track. The machine’s water-filter indicator remains the built-in prompt.

How the S20 filtration stages are arranged

The LifeWell S20 first draws air through a medium-efficiency air filter. Water then passes through PAC, ultrafiltration and carbon block stages. The tank also uses UVC treatment.

These stage names describe the machine’s filtration and treatment sequence. They should not be interpreted as a claim about removing a particular substance or as a percentage-based efficacy claim. The S20 is built to QB/T 5629-2021 and GB 5749-2022 drinking water standards.

The replacement filter set covers the three named water-filter cartridges. Using a set specifically identified for the S20 and shared A10 platform avoids relying on appearance alone when selecting screw-in cartridges.

S20 operating context and ownership costs

The countertop LifeWell S20 requires no plumbing. It is rated to produce up to 2.6 gallons (10 L) of drinking water a day at 86°F (30°C) and 80% relative humidity. Atmospheric water generator output depends on air humidity and temperature and falls in dry or cold air. Its operating range is 41–90°F (5–32°C) and 35–90% relative humidity.

The machine has a 0.9-gallon (3.5 L) collection tank and a 0.4-gallon (1.5 L) drinking tank. It dispenses water at 50–57°F (10–14°C) at up to about 40 oz/min (1.2 L/min).

The S20 is listed at $1,199.95 on Amazon, with free shipping and returns. Through the lifewellshop.com checkout, monthly payments start at $54.96 per month for 36 months with Affirm or Klarna. Replacement filters are a separate recurring ownership cost.

An atmospheric water generator is not automatically the lowest-cost option for every home. Wherever tap water is available, reverse osmosis is far cheaper per liter. An AWG instead offers a no-plumbing approach that makes water from moisture in the surrounding air, subject to temperature and humidity conditions. The guide to atmospheric water generators versus reverse osmosis explains that tradeoff in more detail.

A practical next step

Confirm the machine’s model and cartridge layout before ordering, then choose between the one-time filter set and six-month subscription. Readers evaluating the machine itself can review the LifeWell S20 specs and price alongside its replacement-filter requirements.
