For the fan in the window

I use this for the box fan in my windows. Definitely helps cut on some bad air blowing in. Usually after 4 weeks I can see from the filter what dirty air it's helping to help filter out

Great quality for a great price!

For the price and quality, you cannot do better than these. First, these filters last 3 months--as opposed to the cheaper monthly filters. In the end, these are a better deal per month than the cheaper versions. Second, a lot of the areas where I install the filters are in the ceiling--the cheaper ones just fall out and are difficult to get to stay--love the solid frame and sturdiness. Lastly, they provide great air flow and work great with pets. Highly recommend!

BEST QUALITY AND VALUE

Filtrete air filters MPR 300/MERV5 are the best quality and value for air filters inside your home. I've researched filters for HVAC/Central heat and air units and in Tallahassee the MERV 5 is sufficient for filtering the air inside the home. Unless you smoke inside the home, have lots of pets, mold, pollen, smog, or exhaust ... the MERV 5 will do the job! I have normal household dust, lint, and the MERV 5 even filters dust mite particles that come from household dust. So save your money and try Filtrete MERV 5 filters! I won't pay the higher prices for the filters that cover smog, smoke, mold, etc when I don't have those issues inside my home.
