This filter does a great job of keeping my bedroom air clean and removes the allergens that are bothersome to me. With no pets or smokers in our home, one of these filters usually lasts for 10 to 12 months.
EVEN IF WE DON'T HAVE PETS, I ALWAYS ORDER THE FILTER C. I HAVE AN AIR PURIFIER FOR MY MOM AND IT IS ON 24/7, EVER SINCE I BOUGHT IT HER HEALTH IS MUCH BETTER SO I CHANGE THIS FILTER AS SOON AS THE LIGHTS INDICATES A CHANGE
We have 2 boxer dogs and I run my purifier for about 5-6 hours a day. I have been able to use the same filter for the 7 months before needing a new one. I love the ease of changing these filter out. They are thick and really hold a lot of impurities. I will never use another filter for my air purifier.
