My house was feeling stuffy. The air quality had rapidly deteriorated. The old filters from another vendor continued to whistle though allegedly the correct dimensions. Up the ladder I went, 10 feet in the air and changed the old for the new. It took only a short time to sense the air changing. What a pleasure! My wifes asthma improved dramatically.Thank you!

My only regret is that I didn't know about Filterbuy sooner! I ordered the MERV 13 which is very hard to find these days in stores. Nice sturdy frame. Everything about this filter is superb to anything I could have purchased locally. You have me as a new customer!
