Review on 🌬️ Aprilaire 313 Whole Home Air Purifier Filter by Isaac Simpson

April 1st, 2020 I love this 313 filter! I've been using it for 6 years now. Working in the air conditioning industry, I know how important it is to keep the air conditioner clean. Not only will this make your home cleaner, but it will also prevent dust and dirt from getting into the AC coil and fan. This helps extend the life of the speaker. The filter should last up to 1 year. I found after about 9 months it was time to replace it. Now I change it every 6 months because it's easier to remember. My sister-in-law has many allergies. She can tell the difference in my house when she comes to visit. worth your money!
