Why are my filters slowing down before the suggested lifespan?
Why are my filters slowing down before the suggested lifespan?
Factors like hard or highly contaminated tap water, heavy sediment, or frequent use can cause your filters to slow down sooner than expected. This is because the filters are capturing more material than typical municipal water, and as it works harder to remove contaminants, the available space for water to pass through becomes filled. While the water flow may slow, this doesn’t mean the filters are defective—it means it’s doing its job effectively. The more contaminants and materials it captures, the sooner it will need to be replaced.
Do the filters remove the same contaminants regardless of which set I buy?
Do the filters remove the same contaminants regardless of which set I buy?
Yes, all our replacement filters are designed to provide the same high level of filtration, removing chlorine, PFAS, and particulates while maintaining excellent water flow.

Customer Reviews
The cartridges are really easy to replace, which is nice. I can see the filter changing color over time making me think its working. All great things, but just be ready to change the filters quickly. They do not "ensure monthS of clean contaminant-free water" for my household of two. The water pressure goes down immensely within a month when I'm forced to change the filter.
I order the filter and replacements in December and fitted my shower easily by the end of December. It is now March and I am replacing the filters for the SECOND time. I am getting way less than 8,000 gallons per filter in a household of two. The site makes sure to put an asterisk by that number to make sure they aren't held to that standard (depending on local water conditions). I live in the Great Lakes Region and have looked up my local water's conditions. I'd think the filters would last more than a month.
I'll probably order more in the meantime but for the price and the mandatory fast changing filter situation for me, continuously buying longterm unfortunately might not be sustainable for me or the average household.
Looks way better than Aquabliss and it maintains pressure with a ceiling mounted setup. Water feels soft and I no longer have red eyes from showering.
Our water had a heavy chlorine smell here in Colorado and was drying and irritating to our skin.
Thanks to your product our skin is less dry and itchy, resulting in a much better quality of sleep after our evening shower!
These WORK! Hairdresser approved! Just think, all that brown (shown in the picture of the old filter) was going on your skin and in your hair before! I can tell a big difference in my water quality! I like that you can see these filters working and know when they need changing. I used to be able to smell the harsh chlorine smell in my water when I turned my shower on, not now with the weddell filter attached. It does what it is supposed to do!
Great product, easy install, 30 day return, great sale price, lifetime warranty, and gets rid of contaminates
