Can I use the wrong size air filter?
When you use the wrong size air filter, or you install it incorrectly, the filter can’t effectively prevent dust from accumulating on the system’s motors and blowers. You’ll end up with a dirty furnace that can’t properly perform, and all of that debris could end up harming the system’s internal components.2016-11-09
Can I use a 4 inch filter instead of 5?
Going down in thickness by an inch shouldn’t be a big deal – for example, you should be able to use a 4-inch filter instead of a 5-inch filter. If you are considering a thicker air filter in order to improve air quality it may be better to focus on the MERV rating.
Is MERV 13 enough 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.2022-03-21
Can my HVAC handle MERV 14?
Most residential HVAC systems aren’t rated to handle the amount of strain MERV 14 puts on them. Because MERV 14 has a tighter filter, it requires more force from your HVAC unit. So if you’re using a filter with holes that are smaller than recommended (such as a MERV 14), you’re essentially plugging up your HVAC system.
What MERV Can my furnace handle?
If your family has health or allergy issues, then you may want to look for a high-efficiency filter that’s MERV 11 or higher. But for most households, a MERV 7 or 8 filter might be the sweet spot between performance and cost.
What happens if you use the wrong size air filter?
The biggest concern when you use the wrong size air filter is that it may not effectively prevent dust from building up on your HVAC system’s motors and blowers. This dirties up your furnace which could affect its performance or possibly harm the system’s internal components, leading to costly repairs or replacements.2021-01-18
Is MERV 13 too high for residential?
Minimum Particle Size 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.2019-09-20
What happens if air filter is too small?
If the filter is too small, it won’t cover the entire space and may allow dust and dirt to flow past. If you’re not sure what size filter you need, check the manufacturer’s specifications or ask your HVAC technician for help choosing the right product.2020-05-05
How do I find my max MERV rating?
To determine the best MERV rating for your home and HVAC system, start with the owner’s manual. Look in the manual for the listed maximum MERV rating. Using a filter with a value higher than the recommended limit immediately affects the system’s efficiency and will ultimately lead to costly future repairs.2017-11-02
Will MERV 11 hurt my furnace?
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.
Can I use a 2 inch filter instead of a 1-inch filter?
The higher the MERV rating, the better the filter is at stopping the particles. This means that a 1-inch filter with a high MERV rating could work just as well as a 2-inch filter with the same rating.
Can I use 20x25x4 instead of 20x25x4 5?
No, the 20x25x5 is an inch wider than the other one and would not fit in the slot made for the 20x25x4. The reverse may work, but would likely allow too much air leakage around the filter. 1 of 3 found this helpful. Do you?
Can I use a different size furnace filter?
If your current furnace only allows for furnace filter sizes with a depth of one inch, HVAC contractors can modify the furnace to accommodate larger sizes. This does take work and time. However, homeowners get to use better furnace filter sizes that do more for home comfort.
What MERV is too high?
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.2019-09-20
Will a MERV 13 filter hurt my furnace?
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.
Can I use a 2 filter instead of 1?
If your system only fits a 1-inch or 2-inch filter, a high MERV rating could be detrimental. A 1-inch filter with less surface space will get clogged fairly quickly and need to be replaced much sooner than a thicker filter.
How do you find the MERV rating of a filter?
To determine MERV ratings, air filters are put through two primary tests: The Dust Spot Efficiency Test, which measures the ability of the filter to remove atmospheric dust particles from the air, and the Arrestance Test, which measures the filter’s ability to remove synthetic particles that have been injected into the
Will MERV 13 hurt 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.
