What are Furnace Filters?
Understanding furnace filters is key for healthy indoor air quality. They trap dust and debris to stop them from circulating. The better the filter, the cleaner the air.
Different filters need different installation methods.
- Panel-shaped filters usually slide into a slot near the blower motor.
- Arrows on the filter show which side to face the blower.
- Fiberglass filters are easy to install, but they offer basic filtration compared to MERV or HEPA filters.
Size matters too! An oversized or undersized filter can reduce airflow or let particles escape.
Mark each change with a date and keep track of any issues. Change them out every few months (or as recommended) for the best air quality.
Choosing furnace filter types is like choosing between exes; pick the one that’s not too bad!
Types Of Furnace Filters.
To understand the different types of furnace filters, use these solutions briefly to help improve your home’s indoor air quality.
Fiberglass filters, pleated filters, electrostatic filters, and HEPA filters; each have their way of capturing dust and particles and ensuring your furnace or air conditioner runs smoothly.
Understanding which type to use will save you time, money, and energy.
- Fiberglass filters are a popular choice for their cost-effectiveness and dust-holding capacity.
- They’re made of spun glass fibers that catch airborne particles. They come in different sizes, thicknesses, and MERV ratings.
- But pleated and higher-grade filters can provide better efficiency.
- Pleated filters offer a bigger surface area for particle capture than fiberglass filters, without reducing airflow.
- MERV-rated filters, like 11-13, can get rid of smaller particles like pollen and bacteria.
Regular maintenance can help the performance of fiberglass filters.
A friend found that out after switching back from an expensive MERV 13 filter. Her high-efficiency system couldn’t handle the thicker filter media, causing her condenser coil to ice over.
It’s important to check your system’s tech specs when choosing an HVAC filter.
- Pleated filters can be a great way to filter air for your furnace.
- The folds mean more surface area, so they can capture more dust and particles than a flat filter.
- Plus, they last longer before needing replacement.
- When selecting a filter, pleated ones come in varying thicknesses and materials.
- They may be more expensive than flat filters, but their capability to filter more makes it worth it.
Dr. Harold Hirsch invented pleated filters in 1943 for use in gas masks. Now, they’re used in homes and businesses to keep the air clean and fresh in small apartments to large commercial areas.
If you’re seeking a spark to your furnace filter, try an electrostatic one! It’ll zap away those particles.
- Using advanced static electricity, Electrostatic air filters are great for trapping airborne particles and allergens.
- They are more efficient than other filter types and have a durable design.
- These filters can be washed or vacuumed to get rid of accumulated debris.
- Electrostatic Filters are great for individuals with allergies or respiratory issues. Unlike traditional filters, they don’t restrict airflow and offer quiet operation.
- However, they must be handled carefully to prevent damage to the delicate mechanism.
Air Purifier Ratings stated that Electrostatic air filters can reduce small particle emissions from power plants by up to 35 percent.
Overall, Electrostatic Filters are perfect for those with air sensitivities. They provide superior filtration while maintaining proper airflow.
If you want clean air, HEPA filters are the way to go.
HEPA Filters, or High-efficiency Particulate Air Filters, are great for keeping the air inside homes clean! They can trap microscopic particles smaller than 0.3 microns with up to 99.97% efficiency.
Here are six facts about HEPA Filters:
- They use both physical and mechanical methods to capture particles.
- They are good at catching pollen, dust mites, and pet dander.
- Never wash or vacuum them; it’ll damage the fibers and reduce their effectiveness.
- HEPA Filters will increase energy consumption, but protect HVAC systems from corrosion, fouling, and early failure.
- Replace them regularly, as they don’t last forever.
- HEPA Filters come with different ratings that show how effective they are against particle sizes.
Get HEPA air purifiers with activated carbon or UV lamps for added benefits!
They can neutralize airborne bacteria and viruses, without releasing ozone.
I once knew a guy who used cheap furnace filters to save money. As a result, he got persistent allergies from the dirty air in his home. He switched to HEPA Furnace Filters and his allergies vanished in just 3 months!
So, don’t go for the cheapest option if you want to avoid breathing in dust and allergens.
