Questions On Air and Water Filter Purifiers
Friday February 17th 2012
Good job with the video. My only beef is you should change your air filter at least 4 times a year especially if you get a lower end air filter and not the expensive Filtrete ones.
Thank so much! I’ve had the filter in backwards for a while now. My son has allergies and I’ve been wondering why lately he seems to have such a hard time breathing!
Great work!
thanks I appreciate it
Thanks sooo much, this video is very informative and educative.
Thank you so much! I just changed my filter, and I put it in backwards (and have been doing that for awhile now). I thought that the furnace blew the air into the house so the airflow arrow needed to be pointed away from the furnace (yes, I am a not-so-handy girl). Now I know better! Thanks again for the informative video. =)
