Very Pleased

This was the second time purchasing from All Filters. My system uses a very odd size filter, so I am forced to order online. Same as last time: Great Product, excellent pricing and super fast delivery.

So Far So Good - Looks Like Standard Filters

By Man in 30s from Weston, FL on 1/26/2021 7:27:47 PM

The delivery delay was a bit of a bummer, however not a measure of quality and efficacy of course. As of currently, been using 1st of 6 filter and no "air quality" difference noticed yet. I have really bad allergies and living in FL definitely makes things worse at times. I am hoping these filters will have a progressively positive effect in the long run. The sizing fit perfectly in the filter compartment of our AC (17.5 x 21 x 1), which is great as this does NOT seem to be a very accessible sizing at most local stores. So far, very pleased with filters and communication from vendor has been excellent and timely. Only time will tell if indoor air quality is indeed made better by this purchase.
