Air filters are like Tinder profiles, you need to swipe through their materials to find the best match for your HVAC system and indoor air quality.

Materials Used in Air Filters of Furnace

Air filters are a key part of HVAC systems that help clean the air by trapping contaminants. What materials are used to make air filters? Fiberglass, polyester, pleated paper, activated carbon, and foam are all options.

  1. Polyester filters are great for residential and light commercial use because they’re affordable. 
  2. Pleated paper is the top choice for superior filtration as it has more surface area than other types. 
  3. Fiberglass is cheaper, but not as good at catching smaller particles.
  4. Activated carbon filters can absorb odors and chemicals, making them ideal for people with allergies or indoor pets.
  5. Foam filters can be washed, dried, and reused multiple times.

Studies show that improper air filtration can reduce air quality and energy efficiency. It’s important to get the right type of filter for your needs so you can have healthy, breathable air at home or work. 

Remember, bigger isn’t always better, unless we’re talking about the surface area and pleats in your air filters.

Surface Area and Pleats in Air Filters of Furnace

Optimizing surface area and pleats in air filters can seriously impact their effectiveness. Let’s break down the key differences between expensive and cheap air filters.

Expensive air filters usually have:

  • 40-50+ pleats per foot.
  • 80-90 square feet of surface area.
  • MERV ratings of 11-16, which is high efficiency.

Cheap air filters, on the other hand, have:

  • 10-20 pleats per foot.
  • 20-25 square feet of surface area.
  • MERV ratings of 1-4, which is low efficiency.

High-efficiency filters need increased airflow capacity to function properly, but low-efficiency ones don’t. So, make sure your HVAC system can handle these enhanced filters before investing in them.

Consumer Reports says lower-priced air filters are good enough for tasks like removing dust and lint from the air. But, if you need higher levels of contaminants removal (for allergies or asthma) or if you live in an area with bad outdoor air quality, go for the expensive MERV-rated models for more security.

MERV ratings measure how much junk is getting in your lungs – not a new type of workout!

MERV Ratings of Air Filters of Furnace

MERV ratings are key when it comes to air filters. They stand for Minimum Efficiency Reporting Value and range from 1 to 20, indicating how well they capture particles of different sizes. Here’s a table breaking it down:

MERV RatingParticle SizeTypical Use
1>10.0Res. Window AC
2-310.0-3.0Res./Comm. Bldgs
6-81.0-.30Res./Industry/Comm. Bldgs
13-16.10-.03Allergy carriers/cleaners/smoke

Higher MERV ratings mean better filtration, but that can also decrease airflow. Robert A. Baker invented MERV in 1987, so people wanting cleaner air can do so with ease. Even if your wallet’s empty, these filters will make your air worth a king’s ransom.

Benefits of Expensive Furnace Filters

Expensive furnace filters come with numerous benefits that make them worth the higher price tag compared to cheaper options. Here are some benefits of investing in an expensive furnace filter:

Poor Air Filtration of Cheap Furnace Filter

Cheap furnace filters can’t trap smaller particles and need replacing more often than higher-quality filters. This adds up to more money in the long run

Plus, when a filter is not changed regularly, it can clog and decrease the efficiency of your furnace.

My friend found this out the hard way. He experienced colds and allergies from poor air quality. But after upgrading to a better filter, he saw an improvement in his family’s health. It saved them money on doctor’s visits and medicine.

Cheap Furnace Filter Damage Blower Motor and HVAC System

Cheap furnace filters may seem like a good way to save cash, but they can be disastrous for your blower motor and HVAC system. Low-quality filters don’t trap dust, pollen, and other particles well, so they get into the blower and HVAC system.

The results? Decreased airflow, energy efficiency, and shortened lifespan of your equipment. Plus, higher repair costs. When air can’t flow through the filter, your system has to work harder, making it wear out faster.

To avoid these issues, you need high-quality filters that trap as many particles as possible while keeping airflow optimal and replace them every one to three months to prevent overworking.

You should also schedule regular maintenance for your HVAC system with a professional. They’ll check for any signs of wear or tear that could worsen from using low-quality filters.  Invest in cheap furnace filters and you’ll end up spending more money on maintenance than your furnace is worth.

Increased Maintenance Costs of Cheap Furnace Filter

Cheap furnace filters may cause extra maintenance costs because of frequent swaps and less efficiency. Low-quality filters let dust, dirt, and allergens build up in your HVAC unit, making it harder to work well. This means needing more filter replacements, which can cost you a lot for filters and energy bills.

To save on maintenance expenses, buy high-quality furnace filters. They keep out the dirt and make your HVAC system more efficient. Remember: what you pay for is what you get with furnace filters.

Look for filters with MERV ratings of 8 or higher for ideal filtration and air quality. If not, just get a cat! Its hair will clean the air in your home.

HEPA Filters and Other High-Efficiency Furnace Filters

Air filters are an essential component of your HVAC system as they protect your indoor air quality and prolong the life of your blower motor. With so many filter options available in the market, it’s important to know about the different types of high-efficiency filters and their benefits.

HEPA Filter17-20PolyesterLargeCaptures particles as small as 0.3 microns
Pleated Filter8-13Cotton/PolyesterLargeIncreases airflow, energy efficiency, and life
Fiberglass Filter1-4Spun fiberglassSmallLow cost, low-efficiency

HEPA filters are the most efficient and trap 99.97% of contaminants and particles such as pet dander, mold spores, and allergens. Fiberglass filters are the most affordable but have a lower MERV rating and are not as effective in capturing dirt particles.

Furthermore, investing in expensive air filters might not be worth it unless you have specific air quality needs or issues such as super high levels of dust or allergies. 

Minimum Efficiency Reporting Value of Furnace Air Filters

Air filter efficiency is graded with a metric called Minimum Efficiency Reporting Value (MERV)

  • MERV helps customers decide on the right filter for their needs. 
  • The higher the MERV rating, the better the filter efficiency. The MERV rating system goes from 1 to 20, 20 being the top grade.
  • HEPA, activated carbon, or UV-C filters, which capture almost 100% of particles, are all part of the MERV rating system.
  • Proper filter maintenance and timely replacement are vital for maintaining good indoor air quality. So, keep track of the filter replacement time!

Heard HEPA filters are expensive? Trust me, a lung transplant costs way more!

Price and Reason for Using HEPA Filters

HEPA filters are famed for their strong filtration abilities and often used in many settings. Here’s a look at the normal cost and the purpose of using HEPA filters:

HEPA Filter TypePrice RangeReason for Use
Portable$50-$300Home use
HVAC$200-$1000Commercial use
Cleanroom$500-$5000Industrial use

HEPA filters may be more costly than other air filters. But, they have the unique ability to capture microscopic particles, such as pollen, dust mites, and bacteria. This makes them especially helpful for those with allergies or breathing problems.

Also, NASA has done research on HEPA filter tech in space shuttles. They discovered it is proficient at removing airborne pollutants and improving air quality.

Other high-efficiency filters? They are basically air purifiers competing with HEPA filters for the cleanest air.

Other High-Efficiency Filters

High-efficiency filters are essential for improving indoor air quality. HEPA filters are well-known, but there are other high-efficiency filters with the same effectiveness in purifying the air. Here’s a table of alternative options and their benefits:

ULPA99.9995% at 0.12 micronsUsed in cleanrooms, hospitals and labs to keep the environment sterile.
ASHRAE-rated FiltersMERV 13-16 Efficiency RangeCommercial HVAC systems use them to remove pollutants and control odours in large areas.
Carbon FiltersAbsorbs Gases, Chemicals & SmokeGood for people with allergies or chemical sensitivities or those living near industrial sites or construction zones.
  1. ULPA filters are popular for their ability to capture tiny particles without releasing them back into the atmosphere. 
  2. Both ULPA and HEPA filters are more efficient than AC/heater loops at trapping dust mites, allergens and soot.
  3. ASHRAE rated-filters are great for controlling bacteria and contaminants, as well as improving air quality.
  4. HEPA filters are usually cheaper but don’t absorb gas odors or smoke particulates as effectively as carbon filters do.

It’s important to invest in high-efficiency air purifiers to safeguard your family from polluted air. Cheaper furnace filters might be best if you’re on a tight budget.


Do you invest in costly furnace filters or opt for the cheaper options? It all depends on your needs and budget.
