RayAir Supply 20x25 Replacement Filter Pads Compatible with Dynamic Air Cleaner 20X25 Refill (3 Pack)

Needed replacement filters and none were availabel locally. I found these, but wasn't sure what size and material I needed. I called the company customer service and they walked me through the options and told me what would be best for my application. Perfict fit, problem solved.

Easy to uninstall and install

Just as good as the expensive ones but... you know... not expensive...I just wish I'd found them sooner. Know in advance, though: they come all folded up in an envelope and, when you take them out of the package, you can get stray little bits of the blue plastic in your eye. So just FYI -- don't be an dummy and open these right by your face. 'Cause seriously -- youch.

Why doesn't a filter have a flow rate/vs pressure and a micron rating?I bought these to match what was in the electronic furnace filter. No useful information, annoying in this age of information and virus concerns.

This is a very good quality product

These air cleaner replacement filters fit my unit perfectly and are 1/2 the cost of the name brand that was recommended by the supplier. They work just fine!!

I’ve been ordering these filters for years on the recommendation of my heating professional and they do what is needed. Delivery was very fast!

Is a satisfactory replacement for the OEM filters and seems to work just as well for a lower price

Fast delivery of product. Using these filters a month already for the first time. no problems so far...
