These filters offer an adequate balance between comfort and efficiency. The pores in the filter are large enough to allow ample airflow but small enough to trap many particles flowing through. People with health issues, compromised immune systems, etc., may have problems with poor indoor air quality.

Every air filter has holes that allow air and particles to pass through. The smaller the holes, the fewer particles that passes through. Higher MERV ratings indicate smaller holes, and therefore a more efficient filter. It is essential to know and understand each of the MERV ratings and how they perform in varying air filters.
How often to change merv 11 filter?
A MERV rating is important because it helps you understand an air filter’s effectiveness so you can choose the right one for your particular needs. For example, if you have someone in your home who suffers from allergies, you may want a higher MERV rating. While you may automatically think that a higher MERV rating means a better air filter, that's not always the case.

With the Filter King filter selection tool, you can mark exactly the size, thickness and MERV rating you are looking for. You need a filter that works well with your home’s system and filters out any known allergens or toxins indoors. Higher-rated MERV filters must not only be able to filter out smaller particles but more of them as well. The table below shows the minimum threshold that a filter must perform in order to obtain a specified MERV rating.
How Do True HEPA Filters Compare to HEPA?
In general, filters with higher MERV ratings are more effective and improve air quality, but they are also more expensive. MERV 10 – MERV 12 air filters are able to trap particles as small as 1 micron such as automobile exhaust, pollen, and mold spores. Homeowners can use several types of air filters in their home’s HVAC system. It is vital that you choose the right filter for your home, as they eliminate particles circulating in the air. He brings expert knowledge of a myriad of home air filtration topics including HVAC filters, filtration efficiency, and indoor air quality. Their filters capture more than 85% of the particles that normally end up in your home’s air.
If you have any questions about picking the right air filter for your home furnace, give Robert B. Payne, Inc. a call, and we’ll be happy to provide our expert opinion. The higher the MERV rating of a filter, the more expensive it will be. While MERV 8 is cheaper, it has good performance in terms of filtering small particles, precisely 3 to 10 microns small.
Is merv 13 too restrictive for residential?
To elaborate, if the HVAC system is compatible with up to a MERV-8 filter, don’t use a MERV-9 through 12 filter. For example, MERV ratings between 5 and 8 are usually typical for homes. So, if your system works with up to a MERV-8 filter, get a MERV-8 . Our recommendation is to get the highest MERV rating compatible with your furnace, AC unit, or heat pump. When we set out to build a new construction home, we had a lot of research to do.

E1 particles range in the size from 0.3 to 1.0 microns in diameter. Typical particles in this size range are smoke particles and bacteria. Only filters with a rating of MERV 11 or higher are tested with particles in this size range. Some of thebest air filters for allergieshave extra features such as a carbon layer to remove odors.
Disposable Pleated Filters
Additionally, some crafty HVAC pros will put a filter size label near the filter compartment, along with the dates you need to change it. However, UV filters are not the best for filtering out dust particles and other kinds of contaminants, and you should use them in conjunction with a MERV filter. Our Essential+ filter has an initial pressure drop that's slightly higher than the Essential+, but not by anything significant as it comes in at about 0.03 WG.
You’ll find them priced according to the brand, size, and MERV rating. When choosing higher-rated filters you can generally replace them every days. You might spend a little more on the purchase price of these filters, but you won’t need to change them nearly as often, with cleaner air overall.

Use the highest-rated MERV filter your furnace can handle for the best filtration and cleanest indoor air. MERV ratings range from extremely low to exceptionally high . The rating indicates the size of particles the filter can effectively remove from circulating airflow. The MERV rating on an air filter is a critical factor to keep in mind.
Disposable pleated filters are more effective than disposable fiberglass filters, and they’re available in higher MERV ratings . Reusable metal filters are more convenient, but much more costly as well. They’re made of polyester or cotton paper sheets and are good at trapping small particles.

MERV stands forMinimum Efficiency Reporting Value.TheMERV rating systemis intended to be used to determine the filter’s ability to remove particulates from the air. While the MERV chart covers 20 levels, these levels can be grouped to give you an idea of what a certain range of levels can capture and how effective each will be. If you're wondering what MERV rating should I use, this section can help you out. FilterBuy even had filter sizes for my furnace unit that I couldn’t find anywhere else.
In general, air filters with higher MERV ratings remove a higher percentage of airborne contaminants, therefore improving your home’s indoor air quality. But does that mean you should just get the air filter with the highest MERV rating? MERV ratings above 16 are commonly used in specialized commercial environments where air filtration is critical, such as hospitals. Conversely, a high MERV rating indicates that the filter does a good job of removing particulates from the air.
