Choosing a New Furnace Filter

When choosing a furnace filter many people seem to forget that their price isn’t the only factor which makes each variety different from the others.

Almost all types of furnace filters are disposable, but they all offer their own unique qualities which could be crucially important for the needs of your family or yourself, especially when it comes to allergies and other conditions or circumstances which exist in your household. So, before you make your decision on your new furnace filter, make sure it’s the one that’s perfect for the whole family.

Disposable pleated

This kind of furnace filter is considered to be the best at eliminating spores and mites from being airborne in your home. Disposable pleated filters need to be replaced more frequently than other types of furnace filters. If they are not properly taken care of and left unreplaced then there is a possibility that the filter may damage to your home’s HVAC system.

Disposable fiberglass

This type of furnace filter is popular because of its relatively low cost and its ability of filtering out large particles, and preventing unwanted debris from entering the air stream.

Disposable electrostatic

A disposable electrostatic filter should be strongly considered if you have pets or children at home or if someone in your household is a smoker. This type of furnace filter is seen as the best for preventing allergens from being in the air as well as small particles. Disposable electrostatic filters are pricier than other alternatives, but if allergies exist in your home then the higher price may be worth it.

Permanent electrostatic

If you see the replacement of a disposable filter to be a waste of money, then a permanent filter is the solution that you may be looking for. These filters have an expected lifetime of six to eight years, so a replacement won’t be an issue for a long while. They can simply  be cleaned in any ordinary washing machine and be put right back into use. A permanent filter does cause for less waste, but is slightly less effective than its disposable counterpart in filtering out small particles and allergens.

Before purchasing any sort of furnace filter it is important to take a look at the specifics of the existing filter already in your home. You should know the measurements of the filter as well as the type. This information is necessary so that you leave the store with the correct furnace filter and for there to be no need for a second trip to the home appliances store.
