Great Product at a Fair Price

By Male in 60s and over from Grand Blanc, MI on 8/6/2025 12:15:59PM

First class final stage 0.5 micron filter. The website is loaded with options on all household filters and easy to navigate. All Filters offers top tier products from multiple manufacturers and various price points. This helped my family meet our fixed income retiree budget requirement when combined with a quantity buy which included free shipping. Online checkout was a breeze and secure. Our purchase arrived sooner than anticipated. The packaging was robust thanks to multi-layer bubble wrap around each filter and the use of thick, single cardboard boxes. The products arrived in perfect condition.
