High velocity means the filter can handle high flow rates. the higher the MERV number the more expensive they tend to be. A minimum MERV # 0f 4 is needed to protect the furnace a good value to help indoor air quality is 8-9 this blocks more with the max @16.
What are high velocity filters?
High velocity filters typically are high capacity filters with heavier reinforcing wire and a heavier frame. These heavy duty filters are often needed in industrial application due to paint, weld smoke, oil mist or other excessive dirt loads that will cause a filter to collapse.
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 13 hurt my furnace?
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.
Is MERV 12 too high?
High MERV filters, specifically MERV 12 to MERV 16 filters, stop more and smaller particles of pollutants, allergens and other junk that leads to bad indoor air quality (IAQ). That’s a fact. The terms “more” and “smaller” are both important when discussing healthy IAQ in your home.
Do thicker furnace filters make your furnace work harder?
For the most part, filters are able to get high MERV ratings by using denser material. However, a denser filter can make it harder for your furnace to push air through, which can decrease your system’s efficiency.
Is a thicker furnace filter better?
As a general rule of thumb, a thicker furnace filter will last longer and can be more efficient. Your system configuration will determine the thickness of the filter that you can use.
Does MERV 11 restrict airflow?
Be aware, too, that some retailers also use their own rating system instead of MERV. A decade ago, it used to be that if you had an HVAC system that used panel filters rated 6 through 9 MERV, putting in a MERV 11 or higher filter would restrict airflow (known as filter pressure drop).
Does MERV 11 hurt HVAC?
In particular, using an air filter with a MERV rating that’s too high can damage the compressor, heat exchanger, and air conditioner coil. In most cases, a MERV 11 air filter isn’t too high for residential use.
What MERV filter does carrier recommend?
Selecting a good quality filter with 12 – 16 MERV to remove a high percentage of offending particulates. Be sure to check your filter at a minimum of once per month.
What is MERV rating for Covid?
What kind of filter should I use in my home HVAC system to help protect my family from COVID-19? 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.
Is MERV 11 OK for my furnace?
Increased usage can lead to more wear and tear, so make sure to regularly maintain your furnace. MERV 11 filters however, are not considered to be too high for residential use. Anything higher than a MERV 11 is designed for commercial or households with family members suffering from respiratory issues.
What MERV Can my furnace handle?
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. US Department of Energy recommends MERV 13.
Is a 4 inch furnace filter better than a 1 inch?
The 4-inch thick air filter has a definite advantage over the 1” filter in terms of longevity, airflow and maximum filtering potential. Thus, if it fits your furnace, then a 4-inch air filter is better than a 1-inch air filter in regards to improving air quality.
Are 2 inch furnace filter better than 1 inch?
Well, the thicker the filter the less restrictive it is. This contributes to a better flow of purified air. This means that 2-inch furnace filters allow a better flow of air than 1-inch filters.
Is MERV 8 or 11 better?
A MERV 11 rated filter captures 85% or better of particles between the sizes of 0.3 and 10 microns. This may not seem like a significant difference compared to the MERV 8 filter, but a MERV 11 is also more capable of capturing between 65% and 79% of smaller particles.
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.
How often should you change Merv 8 filters?
every 3 months
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.
Does MERV 8 filter mold?
A MERV 8 filter traps pollen and dust, but also dust mites and mold spores.
Is MERV 8 or 10 better?
Although it is true that 10 is a larger number than 8, and MERV-10 does capture more particles than MERV-8 captures the question that remains is HOW MUCH more does it capture.
Which is better MERV 8 or MERV 13?
If you have allergies, pets, or live near smoke pollution, choosing a MERV 13 filter is the ideal choice. But if you simply need a filter to trap pollen, dust mites, and hair, a MERV 8 filter should definitely get the job done.
