Air Filter Maintenance Tips

Keeping up with your HVAC system maintenance will help it run better and ensure you're breathing quality air in your home.

How often you replace your Filterbuy 20x25x4 MERV 11 air filters depends on various factors. If you have pets or live in a dusty environment, your filters will probably need to be replaced more regularly. You should inspect your air filter at least monthly.

To clean your HVAC filter:

1. Remove it and gently tap it against a hard surface to dislodge loose dust. 

2. Vacuum the area with a bristle wand. It’s best to do this outdoors so you are not spreading allergens inside your home.

A lot of dirt buildup is a sign it’s time to replace it. You should put in a new filter every three months, even if it doesn’t appear dirty. Clean filters keep your system operating efficiently.

MERV Ratings on your Filter

And now, you may be seeing MERV ratings on air filters. MERV (Minimum Efficiency Reporting Value) is a system used for rating how well a filter collects particles of various sizes.

MERV 11 is 95% effective against airborne particles and suitable for homes with allergy sufferers. It filters out dust, debris, pollen, mold, dander, dust mites even better and can filter out smoke and smog as well.

Highlighting the Features of Filterbuy Air Filters

Filterbuy 20x25x4 MERV 11 pleated air filters are at least 20 times as efficient in capturing dust, allergens, and bacteria as standard fiberglass filters.

These filters have a robust beverage board frame that is resistant to humidity and up to 200° F temperatures, so no warping or weakening from high temperatures.

And for the true magic of filtration, Filterbuy employs a proprietary synthetic electrostatic media. This enhanced material provides a much more effective trapping mechanism for particles than low-cost cotton media, found in other filters.

Frequently Asked Questions

Is MERV 11 too high for residential?

MERV 11 is not too high for most residential homes. It provides excellent filtration for common allergens. Like dust, pollen and pet dander. However, it may slightly reduce airflow in some HVAC systems. So it’s important to ensure your HVAC can handle the increased filtration. It’s a good balance between efficiency and airflow for households with pets or allergies.

How long does a 20x25x4 air filter last?

A 20x25x4 air filter lasts between 6 to 12 months. Depending on factors like indoor air quality, HVAC usage and whether you have pets or live in a high-pollen area. It's best to check the filter every few months to see if it needs replacing sooner.

Does a MERV 11 filter restrict airflow?

A MERV 11 filter can slightly restrict airflow. But in most cases, it won’t significantly affect the efficiency of your HVAC. If your unit is older or has low airflow to begin with, you might notice a drop in performance. Make sure your system is compatible with higher rated filters before using MERV 11.

Is the MERV 11 air filter good?

Yes. A MERV 11 air filter is very effective for residential use. It captures smaller particles, such as pollen, dust, mold spores and pet dander. Making it ideal for homes with allergy sufferers or pets. It strikes a good balance between improving air quality and maintaining adequate airflow.

Is there a downside to high MERV filters?

The main downside of high MERV filters is the potential for restricted airflow. Especially if your HVAC isn’t designed to handle higher rated filters. Reduced airflow can strain the unit. Lowering efficiency and potentially causing wear over time. Always check your HVAC’s specifications before upgrading to a higher MERV filter.

What MERV rating is best for airflow?

A MERV rating between 8 and 11 is best for maintaining good airflow in residential HVAC units. These filters provide effective air cleaning without significantly restricting airflow. This makes them a good balance for most homes.

How often should MERV 11 filters be changed?

MERV 11 filters should be changed every 3 to 6 months. Depending on your home's air quality, usage and whether you have pets or allergies. Regular checks help ensure your filter is still performing well and not overly clogged.

Do expensive air filters last longer?

Expensive air filters come with higher quality materials and thicker filtration. But they don’t necessarily last longer than standard filters. Lifespan depends more on the filter’s size, rating and environmental conditions. Always follow the manufacturer's recommendations for replacement.

Can I use 20x25x4 instead of 20x25x5 filter?

No. The 4-inch filter may fit more loosely in the filter slot. This could allow some air to bypass the filter. This reduces its efficiency. Make sure to check your system's specifications before making the switch.

Which type of air filter will last the longest?

HEPA and thicker pleated filters like those with a MERV rating of 11 or higher. They tend to last longer because they have more surface area to capture particles. Larger filters such as 4- or 5-inch filters, also last longer than thinner 1-inch filters.

Do you really need to change air filters every 3 months?

It’s recommended to change air filters every 3 months for optimal performance. But this can vary depending on factors like air quality, HVAC usage and whether you

have pets or allergies. Homes in areas with poor air quality or high pollen may need to change filters more frequently.

What happens if you don't change the HVAC filter?

If you don’t change the HVAC filter, it becomes clogged with dust and debris. This reduces airflow and forcing your HVAC to work harder. This can lead to higher energy bills, decreased efficiency and causes damage to your HVAC. It can also negatively impact indoor air quality.
