What is hammock filter?
Hammock filters are designed to fit in air conditioning and central heating systems that use a hammock frame. Hammock filters come in a large 20 foot roll, which allows the filter to be cut into the appropriate size for the hammock frame. All hammock filters are 1 inch thick.
Are high MERV filters bad for furnace?
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. If the MERV rating on your furnace is too high, it may force your furnace to work too hard and leave it vulnerable to damages.
Can I put a HEPA filter in my furnace?
A HEPA filter commonly ranks at MERV 17-20. Generally, the highest rating you can safely use in your furnace is MERV 13, but we advise asking a heating and cooling company like Service Experts Heating & Air Conditioning beforehand to prevent damage to your furnace.
Are HEPA furnace filters worth it?
More expensive filters like Pleated Residential filters filter out dust mites, pollen, mold and pet dander and even bacteria and so are worth the money especially for those with severe allergies. HEPA filters filter bacteria and viruses and are worth the extra money for those with respiratory conditions like emphysema.
Can my furnace handle a MERV 13 filter?
The ideal MERV filters for both air filtering and furnace efficiency are 7-13, experts say. These filters can be used without any modifications to your equipment. Higher rated filters allow less air to flow through though and can force your furnace to work harder and possibly malfunction.
Is MERV 11 bad for HVAC?
A MERV 11 air filter has a higher efficiency rating. Meaning, it can capture finer particles and clear more contaminants out of the air. Using an air filter with a MERV rating that’s too high is just as bad as using one that’s too low.
Are 3M filters bad for furnace?
The 3M filter may restrict too much airflow. Anyhow, Furnace Filters only trap large pollutants and dust, don’t expect them to make your house all that much cleaner.
Can I put a thicker filter in my furnace?

What filter should I use in my furnace?
Most residential filters range from 4 to 12. Furnace manufacturers prefer the traditional spun fiberglass ac filters (MERV 2). These filter out enough of the large particles to protect the furnace while providing maximum airflow.
Are 5 furnace filters better than 1?
There is no difference between 1″ and 5″ filters with the same merv rating, in regards to the size of particules filtered. There is a difference in static pressure between the two. The 5″ filter has more physical holes for air to pass through, making it easier for to push through.
Are 4 inch furnace filters worth it?
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.
Does the thickness of your furnace filter matter?
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.
Is it OK to stack furnace filters?
Bottom Line: Putting two filters will not make it last longer but may make you have to replace it earlier, assuming it doesn’t already reduce air flow too much with just the filters.
Do some furnaces need two filters?
However, if you have separate heating and cooling systems, your furnace and air conditioner may require different filters. In terms of function, there is no difference between the two as they’re both designed to serve the same purpose: protect your system from harmful air particles and improve air quality.
Should furnace filter be tight?
How tight should a Furnace Filter fit? When you remove the existing filter, take note of the dimensions printed on its frame. Your new filter will need to match this size for the system to run efficiently. It should fit snugly but not so tight that you can’t easily slide the filter in and out.
Can a furnace have two filters?
If you have more than one HVAC system, then you have more than one air filter. However, it’s also important to note that some HVAC systems, especially larger ones, may have more than one air filter and can even require different sizes.
What happens if you run your furnace without a filter?
A Furnace Without a Filter Creates Poor Air Quality When the furnace sucks in the air, it agitates the particles and then travels into the furnace. The heat from the furnace destroys some of it, but the rest flies through the vents and into the air. It’s now airborne and you and your family breathe it.
