Your furnace filter is a device put in place inside your HVAC system whose purpose is to remove as many impurities as it can from the air that your breathe in your home. This job is of the utmost importance as it can affect not only the performance of your HVAC system but moreover the quality of the air you and your family are breathing. Poor indoor air quality is one of the leasing causes of respiratory problems, so it is important that you keep up with the maintenance of the furnace filter in your home.
So what is it that the furnace filter removes from the air?
Most everyone knows that air filters –be it the one in your furnace, HVAC intake or one of those whole house filters — for the most part trap DUST in them. But what exactly is dust anyways? We kind of just thin of it as its own thing, but dust is actually made up of many nasty little things – the sum of which becomes that greyish nastiness we call dust.
Dust can contain some or all of the following things:
- Small fibers from clothing, carpets and other things
- Pet dander
- HUMAN dander (yes humans have it too, in the form of dead skin cells – over 700,00 of them PER DAY!)
- Mold spores (gross)
- Other random toxins released by things like household cleaning products
Now, if that wasn’t bad enough, what happens is that all this adds up to dust and dust is food for dust mites. When these tiny little mites are in the air, they can trigger allergies and asthma. In one single ounce of dust you can find over 40,00 dust mites!
Your furnace filter is designed to trap all this nastiness that’s floating around in your home so that you and your family don’t breathe it in and run the risk of contracting a respiratory illness.
It’s important that you replace your furnace filter regularly, according to the schedule set forth by the filter’s manufacturer.
All air filters are not created equal
When it comes to air filters, you pretty much get what you pay for. Cheap fiberglass filters may be inexpensive and may make replacing your filter on a regular basis a little more affordable, but what you gain in cost you lose exponentially in effectiveness. Cheap filters are woven so loosely that they are only able to trap very large particles, allowing the smaller and more dangerous ones to pass right through them.
A lot of people think that you should only buy filters that are made by the same manufacturer that made your HVAC system. This is simply not true. An aftermarket furnace filter like those offered at airfilterbuy.com can offer many more features that an OEM product cannot, such as odor blocking and designs that ensure a proper fit and an ease of replacement.
The bottom line is this: your furnace filter is a critical component of your HVAC system. After learning what it is that you and your family could be inhaling while resting comfortably in your home, it becomes clear that making sure you are buying the right filter and replacing it according to the manufacturer’s schedule is a paramount step towards ensuring the health of your family and the safe effective operation of your HVAC system.
