Air filters-  Choosing air filters these days can be overwhelming. There is an entire aisle full of choices at Home Depot and Lowes. Here is what you need to know when choosing an air filter for your home. There are three basic types of disposable filters available:

• Fiberglass- These are the cheapest filter available. They are usually only a dollar or two each and are blue, green, or sometimes white. You can see right through them and they do very little to actually filter the air in your home. HVAC Technicians often joke that these filters only stop trees, leaves, and small children.
  

• Pleated- These are the top of the line filters. They will have ridges or a “wave” pattern to them. They can cost as much as $30 just for one filter and are often labeled as allergy relieving because of their supreme filtering capabilities. These are an excellent choice for folks who suffer from allergies to pollen and dust.

• Poly- These filters are an excellent middle-ground between the others. The cost is just a few dollars a piece, and they do a very good job of filtering your home's air. They are usually white, but you will not be able to see through it. This is what I recommend for most people since they do a great job of filtering the air and don't cost a fortune.
