How much do you know about air filters? Do you know how to choose the right filter for your heating system? In Central Ohio, where most people are running their furnace almost full-time from October to April, you should be changing your HVAC filter every month as part of your regular furnace maintenance. In fact, a dirty filter is the leading cause of equipment failure. 

Many people wait until the dust gathers and takes over their filter, but you shouldn't wait until that happens. It is important to keep a clean filter at all times for health furnace_check.pngreasons and energy efficiency.

When your filter is dirty, your system has to work harder. This can increase your fuel costs and reduce the life of your equipment.  

So how do you know which one is right for you? HVAC filters are categorized into three different types based on their material and purpose: standard mechanical filters, electronic filters, and pleated filters.

Mechanical air filters are the most common type of filters used in homes. The purpose of this filter is to trap dust particles and other debris using synthetic fibers in order for the debris to stop circulating in the air. The disposable fiberglass filters come in two sizes: one and two inch thick filters. You may need to change these filters often because of the adhesive coating and mesh that filters the air coming in usually gets damaged when cleaning.

The next type of air filter is the pleated filter. These filters remove around 35 to 40% of the dust particles in the air. Although they are not as good as the electronic filters, they are better than the mechanical ones because they have more fiber per square inch compared to the disposable fiberglass filters. This is because if there is more fiber in the filter, it is more effective in trapping dirty air particles.

An electronic air filter is the most expensive and best quality filter you can install. This filter is the best for trapping debris and dust in the air; it even goes as far as trapping smaller molecules such as smoke, mold, and pet odors. There are also two sizes that this filter comes in, just like the fiberglass filter. This one also lasts longer than other filters. Electronic filters are good for up to six months and are usually packaged with a pre-filter that traps larger air particles.

The electronic air filter works by charging the air with static energy that attracts dust particles and other debris. In order to be marketed as “allergy free”, they need to be changed every three months. 

If someone in yur home suffers from respiratory issues, going beyond a basic pleated filter and managing your home's indoor air can be very beneficial to their comfort and health. A whole house ventilation system installed as part of your home's heating and cooling system, can expel stale, stagnant air and replaces it with fresh, clean air. 

The air you breathe inside your home could be the most polluted air you breathe all day. In fact, the EPA has named indoor air pollution as one of the top five environmental risks to public health. With the amount of time spent indoors, it's no wonder so many people suffer from allergies, asthma and other illnesses.

HVAC filters are put into these categories because of their MERV ratings. If you are planning to buy a filter, check for the MERV rating first.
