Does My HVAC Need an Air Filter?

Good Deals Heating and Cooling HVAC filterAs you move into your new home, one of the things you’ll want to be mindful of is the HVAC unit. Short for “heating, ventilation, and air conditioning,” this unit is important because it will play an essential role in how comfortable or uncomfortable your home’s climate feels. Heating and cooling are two of the main concerns, but one thing that new homeowners may forget is that the filter used within the HVAC is just as important.

Let’s get the big question out of the way first: do you need to have an HVAC filter for your unit to function? Technically speaking, no you don’t. Air will still push through the system, and your house will cool down or heat up as you desire. However, in the long run, there will be some significant issues that will crop up.

Low-Quality Air

The filter is put into your HVAC for a significant reason: to help filter out airborne particles that are bad for your health. With a filter, mold, dust mites, and other things will not be collected and will run rampant in your house. They can make you sick, and because the particles are circulating in your home, you run the risk of getting sick again and again.

Freon Tube Damage

Your air conditioner functions by having air blown onto the perpetually wet tubes filled with freon. Because they’re wet, anything that wasn’t caught with the filter will get stuck onto them. Eventually, all the gunk will build up, and they won’t function the way they should. Your AC may not cease to produce cool air.

Humidity Level

The filter helps to keep your AC functioning so that water condensation evaporates and doesn’t assist breeding mold and other airborne particles (which are bad for your health). This is also important because if you rely on your AC for dehumidifying your home, it won’t be able to without a filter.

Ductwork Damage

Much like your freon tube, your HVAC’s ductwork will be affected by condensation that collects in its aluminum casing and eventually will have mold spores growing within them. These will travel down from the ductworks and spread across your house via the ventilation shafts. Mold can cause health issues for you and your visitors.

When moving into your new home, we strongly advise that you not only make sure to have a filter in your HVAC for the reasons above but to make sure to change it periodically. We recommend checking it each month and replacing it based on your living situation. If you’re in a climate in which you have the unit on year-round, you may want to change it as often as every one-two months. If you live with multiple pets, you’ll also want to change filters every couple of months due to animal hair and dander floating around. Every three months is recommended for those who don’t use the unit that often. But you should be able to determine which frequency works for you if you’re checking it each month.

What Are The Different Types Of HVAC Air Filters

Good Deals Heating and Cooling HVAC air filtersOne of the most critical parts of your HVAC system is the air filter. The air filter is responsible for keeping the air that enters your home clean of contaminants. Bad air quality can also clog your HVAC system. Understanding the different types of HVAC air filters will help you to determine which is best for your home.

Fiberglass or Synthetic Filters

If you are looking to spend the least amount of money, what you are looking for are fiberglass and synthetic filters. These are both affordable and disposable. Particles 50 microns or larger are filtered out up to 80% by these filters. Particles between the size of 3 and 10 microns are filtered at 25%. BY using these filters, you can filter out dust and dirt but not all harmful contaminants from your home or office.

Polyester Based Filters

Filters made from polyester are one of the highest quality that you can get. Particles at or above 5 microns are filtered between 80 and 95%. You will get extreme filtration but at approximately four times the cost of the fiberglass or synthetic filters mentioned above.

Electrostatic Filters

The fibers in these filters are self-charged to create electrostatic attraction. Both standard versions of electrostatic filters and washable versions are available. Between the two there will be a MERV (Minimum Efficiency Reporting Value) rating of 4 to 10 depending on the specific filter. Washable filters will last longer than disposable filters.

Pleated Filters

For those that desire to catch the smallest particles floating around, the pleated filter is the right option. They can catch particulates that are down to .3 microns in size. That includes most contaminants and allergens. At the same time that pleated air filters give you the best filtration, they allow decent airflow.

HEPA Air Filters

Out of all of the HVAC air filters, a HEPA filter is the most effective. It will capture up to 99% of particles that are .3 microns or above. HEPA filters provide fantastic filtration at the cost of some airflow. Your system will have to work slightly harder when using these filters, costing more money.

Now you know the major types of HVAC air filters out there you can make an informed decision about which one is best for your system. Are you okay with minimum filtration with the benefit of cost saving or do you need something more robust? If you already have an HVAC system in place, make sure that the filter you decide to use is compatible with your system.
