Review on 🌬️ Enhance Indoor Air Quality with Nordic Pure 16X20X4 Pleated Furnace Filter by Cho Screeton

My oven has a Honeywell filtration system. The filter size for this setup is 16" x 20" x 4", but I wasn't aware of the actual product dimensions. Get confused. The actual size of this filter is 15-1/2" x 19-1/2" " x 3-5/8". It is significantly smaller than the filter size required for my device. My system requires a filter size of 15-15/16" x 19-3/4" x 4-3/8" I looked at various brands of filters and was surprised even though they listed as 16" x 20". were "X 4", actual size varies by brand Price is good for 2 filters but not very good when the filter only does half the job.I also found out that Home Depot has a completely different one Rating for filter used than any other Most brands use MERV rating but Home Depot uses so if you buy a filter from Revain you will see a MERV rating, if you go to HD and buy the exact same filter you will see an FPR rating so a filter with a MERV of 8 will not match an FPR of 8. Pictured is a smaller filter which I had to return.With a lower profile and larger gaps around the filter, there is a lot of unfiltered air flowing through the system.
