I love shopping online. I have never been one to really enjoy going to the shops, except, perhaps, when I was quite young and had a good figure and wanted to always be buying new clothes. Anyway, those days are gone, and everything I do to both save money and avoid going to the store, that’s what I do. One thing I have discovered is that it is a good idea to buy things in bulk that I am going to use over and over again. One such thing is a/c air filters. Everyone knows that we are supposed to change our a/c air filters on a regular basis according to the manufacturer’s directions. Usually, that means once a month. Changing out the a/c air filters does a couple of important things. First, the air conditioning unit stays cleaner. The a/c air filter traps the yucky stuff in the air and keeps the dust from getting into the a/c system. Next, good a/c air filters can help you breathe easier by producing good indoor air quality. HEPA air filters are really good at this. The cheaper air filters are not all that great when it comes to helping create good indoor air quality, though. Here’s the thing, though. I often forget to change the a/c air filter. My a/c opening is in the ceiling, and that discourages me, also. I have found that if I buy a/c air filters in bulk, I cut out the need to go to the store to buy one, so I am more likely to replace the dirty air filter like I’m supposed to.
