Filter Set - FS300

€128,95

Please inspect your order upon arrival. Report any breakage within 7 days to receive replacements at no additional cost.

Thank you.

Filter changes are recommended every 1000 gallons or one year, whichever comes first.

Purification performance drops rapidly after one year, and most contaminants are odorless and tasteless. Don't wait until your water tastes bad; that means you've been drinking contaminants for a long time already.

Plus, the filters add magnesium and keep your water alkaline. The magnesium is all consumed within a year.

Check your email for a Filter Change Reminder sent 11 months after your system purchase or your last filter purchase. It includes a $20 filter discount.

When you change your filters on schedule, you're paying just $0.31 per day to have supernatural water on tap at home. Compare our value to any other premium water on the market!

Filter Set FS300 includes everything to replenish your Atla/AquaLiv Water System. Please note that the big tank never needs filters or servicing outside of sanitizing during filter changes.

Atla recommends sanitizing your system as part of the annual filter change process to ensure your system is free of pathogens.

Sani-System sanitizer is designed to clean water systems safely. Sani-System liquid concentrate is efficient and easy to use. It is pre-measured in the correct dose for your system:

Kills 99.9% of harmful bacteria
EPA and NSF approved
Reliable, effective results
Will not damage system seals and o-rings like chlorine/bleach or hydrogen peroxide
Leaves no residue behind
Made in the USA
Will not void your Atla/AquaLiv System warranty

Sanitizing instructions are included with the filter change instructions.

Fits Atla/AquaLiv Water System models A370, A305, and A300.

Does your system consist of two (2) or three (3) independent modules?
Do you have one (1) purification module comprised of three (3) filters?

If yes on both, this cartridge set is for you.

Step-by-step filter change instructions are included with every filter set. You can also download the instructions below.

We Aim to Keep Filter Prices Low

When our water system launched in 2009, replacement filters were $99 with free shipping.

According to the US Inflation Calculator, a product that cost $99 in 2009 will cost $148.34 in 2025.

However, in 2009, we didn't offer a $20 discount to customers who replaced their filters annually.

As a result, most of our customers today pay 19% less for replacement filters than they did when our water system launched in 2009.

Plus, these aren't the cheap filters our competitors use. Each Atla filter set contains over 4 pounds of filtration media and lasts 1 year, unlike other filters that last only 6 months.

When you purchase filters with your annual discount, you're paying just $0.31 per day to have supernatural water on tap at home. Compare our value to any other premium water on the market!
