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.
