Box Fan Air Purifier
on August 26, 2021

I used the four inch Merv 13 air filter to make a low cost box fan air purifier. Air flow is much less restricted using the four inch FilterBuy filter compared to the one inch filters available at my local stores.

Size issue very confusing. 16x25x4 too small, did not fit. See photo. Note difference in sizing. Received refund with little problems. Thank you.

Great purchase!

It was convenient to order multiple filters online. It is difficult to find the size I need in stores. Now I will order in bulk online via Filterbuy. The price is reasonable and my size was available. I am happy that my online search for filters led me to Filterbuy!
