Nice Weather Today
Have you checked your filter today? How about you HVAC registers?? See any dirt, cobwebs, little dead critters around the air diffusers? Time to clean around them with a vacuum cleaner and make sure no more reappear.

Pleated Filters
There is quite an array of pleated filters on the market right now. Most HVAC contractors will provide a good cost effective choice with their maintenance agreements. A 1" pleated filter with spun media is what one would see most of the time for residential use. The pleated design allows more surface area for particles to be trapped on and allows for a tighter weave of material. These filters are said to allow for 90 days between changing--however if there is massive amounts of large particles the filters will clog and diminish air flow quite rapidly. Make sure you check the filter if there is any construction, roadwork, or extreme dust conditions around the house.
Next time: washable filters.

Disposable filters
Well most homeowners know there is a filter somewhere in the HVAC system--sometimes they forget about it till things don't work so well. I've had some pull right into the blower of the furnace because they were coated with hair and dirt. Other times on service calls, the homeowner doesn't have a clue where it is. We'll cover placement in another post.
Are the cheap 99 cent filters effective or not?
The fiberglass filters priced usually around 1.00--2.00 will stop most large particles, hair, large drywall particles, and household dust particles. However all heavier finer particles go right through.
For instance fine powdery dirt, pollens, molds, yeast spores go to your HVAC system, and of course gather on ducts, coils, heat exchangers, blowers, etc. The cheaper filters also pass the dirt through when the are full. These need to be changed every 30 days at a minimum.
Next time we'll look at the pleated types.
