I purchase new filters monthly during the winter to keep the air in my home as free of dust particles as possible. I find the Filtrete products are high quality and I trust them completely. They are the only home air filters that I purchase. When I find the best, there is no need try anything else. Please don't change anything!!!
I am a stickler for chaning my filter every 90 days. Sometime if we are doing home remodeling I will change it more frequently. I am always impressed by the amount of dirt and dust on the old filter. I feel confident putting in a new filter that it will do a great job of catching the dust and pollen. My home is pretty much dust free!
Used to use old disposable filters. Switched to this filter for much better filtration for my home. Cost more but much cleaner air. Also good for 3 months. Would recommend..good value for the money
