Filters ordered were supposed to be 20x24x1. They are actually 1/8 to 3/16 less all around. Easy to put in, but are they large enough to actually correctly seal the airflow, do they allow too much leakage around the edges? Personally, I don't like to have to force them in, but I only have to do that once a month, so how much bother is that? I am not really satisfied, and would recommend AGAINST anyone buying them because they think that they are buying a premium filter. They do not seal well.
Filters are made well and are very affordable. I usually keep several filters on hand. I was looking at filters in different stores and thought my goodness they are high priced for no more than what they are. That's when I came across FilterBuy. Couldn't be happier with the quality and price !!!!
Weve been so pleased with these filters. Its amazing the decrease in the amount of dust we saw with other filters and how much better the HVAC systems run. Amazing.
