Quick Answer: How Often Should Merv 13 Filters Be Changed

Table of Contents

For Merv 8, 11 and 13 filters, we recommend that you change your filter at least every 3 months, however changing your filter every 2 months provides better filtration which provides healthier and cleaner air in your home.

Are MERV 13 filters worth it?

A MERV 13 filter is a step in the right direction and captures more particles than a typical MERV 8 filter. However, it is not as good at capturing small virus sized particles like a HEPA can. A MERV 13 will trap less than 75% of air particles that are 0.3-1.0 micron in size (the coronavirus is 0.1 microns).

Can a MERV 13 filter be washed?

A: Yes. After using the mask in public, the mask should be cleaned or sterilized. If you need to wash the mask, remove the filter material and hand wash. Machine washing tends to crumple the nose wire which will cause it to eventually break.

Is MERV 13 enough for Covid?

Minimum Efficiency Reporting Values, or MERV, reports a filter’s ability to capture particles. Filters with MERV-13 or higher ratings can trap smaller particles, including viruses. By itself, using an upgraded HVAC filter is not enough to protect people from COVID-19.

Is MERV 13 too much?

Filters within a MERV rating of 17-20 are almost never necessary in a residential home. A MERV rating of 13-16 is considered hospital level air quality, so it is unlikely your home needs any more than that.

How long do MERV filters last?

The basic recommendation for furnace filters replacement is every 3-4 months for MERV 8, every 6 months MERV 10 and 11 and every year for MERV 16.

How often should MERV 15 filters be changed?

Your furnace’s owner’s manual will specify the best MERV rating for your furnace, and in general, filters with a MERV rating of 6 through 9 should be changed every 90 days, while those with a MERV rating of 10 through 12 should be changed every 60 days.

Will a MERV 13 filter hurt my AC?

MERV 13 air filters are the highest-rated air filters for home use. Any air filter with a rating higher than 13 will restrict air flow to the point of which could cause damage to your HVAC system, resulting in an added expense to fix it.

How often should HVAC filters be changed?

How Often Do I Need to Change Out My Air Filter? Generally, most air filter manufacturers and HVAC companies recommend changing your air filter every 90 days, or 3 months.

Is MERV 11 or 13 better?

A MERV 11 rated furnace filter can trap the majority of harmful contaminants that are present in the air. A MERV 13 filter is capable of filtering out all particle impurities like dust, lint, pollen, mold, dust mites, pet dander, smog, and smoke. On top of this, it can also trap bacteria and viruses.

What is the difference between MERV 12 and MERV 13?

MERV 10 – MERV 12 filters remove most 1.0 to 3.0 micron particles plus bigger ones. These include all those listed under MERV 8 filters plus pet dander, bacteria, most smoke/smog particles and most auto emission particles. MERV 13 – MERV 16 filters remove most . 3 – 1.0 micron particles plus bigger ones.

What is a MERV 13 mask?

Good Protection: MERV 13 Filter Media uses a synthetic media that is electrostatically charged, capturing 98% of airborne pollutants and fine particles as small as 0.3 microns. Filtered contaminates include pet dander, lint, fine dust, dust mites, dirt, mold spores, pollen, smoke, harmful bacteria and viruses.

Is it okay to vacuum air filters?

Vacuuming a Filter Can’t Reach the Inner Fibers The contaminant particles can get buried deep in the filter’s fibers, so a vacuum cleaner won’t extract all of them. The particles will create a barrier in the air filter and prevent air from passing through, which could damage your HVAC system or make it less efficient.

Can I vacuum AC filter?

Vacuum the Filter If your central air filter shows no signs of grime buildup, you can use the hose attachment from your vacuum cleaner or use a handheld vacuum to remove any debris. If the vacuum hose doesn’t remove the buildup, you will need to wash it.

How many microns does MERV 13 filter?

MERV 13 filters are a step up from the MERV 8 or 9 rating. A MERV 13 filter can capture less than 75 percent of air particles that are 0.3 to 1.0 micron in size.

Can I use a MERV 13 filter in my furnace?

MERV 13 is the highest MERV value safe for residential furnaces; the higher ratings are used primarily in commercial units. If you are wondering what MERV to try, keep these recommendations in mind; ASHRAE recommends MERV 6 or higher.

Can my furnace handle a MERV 13 filter?

The ideal MERV filters for both air filtering and furnace efficiency are 7-13, experts say. These filters can be used without any modifications to your equipment. Your system may handle MERV 14-16 with no discernable stress. However, many residential systems require modifications to pull air through these filters.

Is MERV 13 good for residential?

According to the ASHRAE, the best rating for residential HVAC systems is MERV 13. But before you upgrade your filter, make sure your specific system can accommodate that rating. A higher MERV rating often means lower airflow, which can cause the system to work harder—use more energy—to do its job.

How long does a MERV 13 filter last?

What are MERV 13 filters made of?

For example, the filter media in our MERV 13 pleated filters is made of polypropylene/acrylic fibers. This high-quality, synthetic, plastic-based material allows the filters to trap particles as small as lint, dust mites, mold spores, pollen, pet dander, fine dust, smoke, viruses, and bacteria.
