While fiberglass air filters will do the job in the most basic way, in most cases, pleated air filters are much better. They can filter out smaller particles – important for people with airborne sensitivities. They are less likely to clog in a short amount of time, and they can last up to 90 days.

What is the best material to filter air?

Activated carbon is considered one of the safest, most reliable air filter materials available today.

Are non pleated air filters better?

A pleated filter is made up of different sizes, and readily captures pathogens as small as 0.3 microns, filtering out even the tiniest of bacteria. They are overall more effective in capturing very tiny particles than non-pleated air filters; 99.97% of airborne particles are trapped with a pleated air filter.

Are pleated filters bad for your furnace?

Pleated filters are bad for your system because they block too much air, forcing the HVAC motor to work harder to pull in the air it needs and burning it out faster.

Do pleated filters last longer?

Pleated air filters are more expensive at the outset, but they are also more efficient at trapping particles and can last up to 90 days, depending on use.

Pleated vs Fiberglass Air Filter Demonstration

Is fiberglass filter better?

While fiberglass air filters will do the job in the most basic way, in most cases, pleated air filters are much better. They can filter out smaller particles – important for people with airborne sensitivities. They are less likely to clog in a short amount of time, and they can last up to 90 days.

What filters do HVAC techs recommend?

HEPA Filter — HVAC replacement companies typically recommend HEPA filters because they can provide the highest protection level when it comes to airborne particles. This filter is capable of capturing small microns, and has a MERV rating between 17 and 20, meaning it can trap tobacco smoke and bacteria.

Which filter is best for furnace?

Top 5 Furnace Filters

• Best For Large Systems: Filtrete 20x25x1 AC Furnace Air Filter.
• Best Value: Filtrete 10x20x1 AC Furnace Air Filter.
• Best For Small Particles: Aerostar 12x12x1 MERV 13 Pleated Air Filter.
• Best For Allergies: Nordic Pure 16x25x1 MERV 12 Pleated AC Furnace Air Filter.

Do pleated filters reduce airflow?

Even though pleated fiberglass filters are very common and are continuously highly recommended, there's still a misconception around the filters being able to cause damage to your unit because they supposedly restrict air flow. Yes, pleated air filters do indeed restrict the airflow to your HVAC system.

How long do pleated furnace filters last?

High-end pleated filters can last as long as 6 months, but these typical guidelines assume average use and don't take into account the size and type of filter. As a general rule, you'll want to replace pleated air filters and furnace filters in your home every 90 days.

How long do fiberglass filters last?

Unlike many advanced filters that can last 3 months or more, fiberglass filters are only designed to last for 30 days at a time. After 30 days, they lose effectiveness and need to be replaced.

How efficient is a pleated filter?

Better HVAC Protection

The average efficiency of a pleated air filter ranges between 25% and 30%, but it may go up to 45% in the case of carbon material.

What MERV are fiberglass filters?

Disposable fiberglass: These filters typically have MERV ratings of 1-4. They have the capability to prevent large particles from getting into your system. While disposable fiberglass filters are inexpensive, costing a couple of dollars at most, they won't do much to improve indoor air quality.

What are 3 different types of air filters?

Here are the three main types of air filters:

• Fiberglass Filters. This type of filter consists of layered fiberglass fibers laid over each other. ...
• Pleated Air Filters. A pleated or polyester filter is usually a significant step up from a fiberglass filter. ...
• HEPA Filters.

What type of home air filter is the most effective at blocking pollutants?

1. HEPA Filters. High-efficiency particulate air (HEPA) filters are recommended by the U.S. Department of Health because they are able to remove at least 99.97% of airborne allergens and pollutants — including mold spores and dust that are as small as 0.3 microns.

Which filter media is best?

The Best bio filter media

• Biohome Ultimate Filter Media.
• Seachem Matrix Bio Media.
• Fluval Biomax Bio Rings.
• Marineland Bio-Filter Balls.
• EHEIM Substrat Pro Biological Filter Media.

Is there a downside to high MERV filters?

Wrong. While the highest MERV ratings are the most effective for air quality, they can harm your HVAC system. A higher MERV rating means a higher resistance, which means less airflow. When researching HVAC systems, airflow will come up a lot.

Will MERV 12 hurt my furnace?

The short answer is that it can, but it's not really an issue except under extreme circumstances. Most modern HVAC systems have no problem working with higher MERV filters, which is why millions of homeowners depend on them.

Is MERV 11 too high for home?

In most cases, a MERV 11 air filter isn't too high for residential use. Generally speaking, anything under a MERV 13 air filter should provide very efficient air purification in a home without impacting airflow.

Are more expensive furnace filters worth it?

Yes, in general, the more expensive air filters are more effective, but a single person with no pets and allergies might not need as much filtration as a family of five with three pets and a child with asthma. Also consider how long your air filter will last.

What MERV rating is best for home use?

In general, the best MERV rating for a home is somewhere between 8-10. These filters will capture a large portion of the airborne particles and improve indoor air quality without making your energy costs rise significantly.

Are thicker furnace filters better?

Thicker air filters tend to last longer because they have more square footage to capture and hold air particles. To put it in perspective, a 1-inch air filter may need to be changed every month whereas a 4-inch air filter could last up to six months.

Do I need filters in my return vents?

In general, it is recommended to have an air filter in every return vent (as long as you choose the one of the right size and thickness). The filters will improve the air quality in your house and will protect the HVAC equipment from dust, pollen, pet dander, and hair.

Does it matter what type of air filter you use?

The short answer is, no, they're not all the same. In fact, there are many different types of air filters available and choosing the right one can make a real difference in the lifespan of your HVAC system.

Is MERV 11 or 13 better?

MERV 11 furnace filters have a particle arrestance of a little over 90%. In comparison, MERV 13 HVAC filters have a particle arrestance of around 98%. Naturally, it is significantly more efficient. MERV 11 rated air filters are ideal for those who live in a moderately polluted area, have mild allergies, or own a pet.
