Are expensive air 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..

How do I choose an air filter?

Size, MERV rating and material – these are the three primary factors used to pick the proper air filter for your home.

1. 1) Filter Size.
2. 2) Material & MERV Rating.
3. Rating Average Filtration Efficiency.
4. Be Careful About High MERV Ratings.

What MERV rating is best for allergies?

Ideally you want to choose a MERV rating of 17 or higher, which are most effective at blocking the particles that cause allergy symptoms.

Which MERV rating is best?

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.

Are thicker air filters better?

Most air filters are 1 inch thick, but some systems can accommodate filters 2 to 5 inches thick. In our tests, we found that the thicker the filter, the better it works and the longer the replacement intervals. That means it’s better for you and for your heating, ventilating, and air conditioning (HVAC) system.

Will MERV 11 hurt my AC?

Is MERV 13 too high for residential?

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.

Are pleated air filters 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.

Is MERV 14 too high? The abbreviation stands for Minimum Effective Reporting Value. In other words, it’s a measurement showing how small the holes are in the filter. The higher the MERV number, the smaller the holes, and the less that can pass through. Ultimately, this is what makes MERV 14 filters not a good choice for home use.

How much should you spend on an air filter?

You can spend anywhere from $15-$30 for a disposable filter that, in reality, needs to be replaced every 30-40 days. The filters in a whole home air purification system only need be changed out once per year on average, saving you between $180-$360 in disposable filter replacement costs each year.

Do air filters really make a difference?

Research shows that filtering the air can indeed help to remove harmful particles from indoor spaces, particularly allergens, smoke, and mold. Still, air purifiers work best in conjunction with proper filtration and home cleaning techniques.

Will MERV 13 damage my HVAC?

What Are MERV 13 Air Filters? 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.

Are Filtrete filters worth it? CR’s take: The Filtrete 1900 Maximum Allergen Reduction filter is impressive at removing dust, pollen, and smoke from the air when the HVAC system is running on its highest fan speed, earning an Excellent rating in that test. But at the lowest speed, the filter is only average at removing those same airborne particles.

How much should a HEPA filter cost? How much does a HEPA filter cost? HEPA filters vary in cost and range from $16–$95 depending on quality, estimated longevity, and manufacturer. Air purifiers that rely on HEPA filters range from $50–$1,000 depending on size, quality, and projected coverage area.

Avoid wringing or stretching the filter – they can tear easily.

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.

Is MERV 11 too high?
