A few days ago my wife and I went to WalMart to purchase another Filtrete Brand top of the line filter. They did not have my size ( 16x 20 x1). So I purchased your Purity product with the intent of using it only until I can get a Filtrete Filter. I had to cust it to size and had somewhat of a time getting it in the furnace, but on day two of use, the Purity Filter that cost less than half the price of the Filterete Filter, completely removed a serious MOLD problem we've been dealing with in our furnace and vent system. I was in no way expecting the results we got. The MOld Problem in our house has been so bad we've been changing filters very often with only little results. It was so bad we were considering moving out of the house.
We have a room closed off that had a leak problem. What we've been dealing with is the MOLD that has leaked into the other areas of our home before the room was sealed off. The MOLD problem was serious enough to cause health issues.
day two: My breathing has improved. The air seems clean and my nasal eyes are getting better. So much has improved in just two days. Plus it is allowing more air to move through the furnace.
I dont quite understand the filter, but do not for sure it is without a double the best thing out there for serious MOLD problems.
Thank you so much for this product.
