Safeguard Window Filters

Product Review (submitted on April 9, 2015):

The filter is too tight for air to pass through. While it's true water can't get through -- air can't really get through, either. On several occasions, the filters would actually get sucked into the house because of the air pressure force from the whole-house fan. You could barely feel a breeze in front of the filters (with a huge house-fan sucking air out of the house)... without the fan, there was absolutely no airflow at all. We had much better results by fashioning a 'homemade' filter using two standard anti-allergen HVAC filters duct-taped together. This is a great concept, but you get what you pay for...
