What is the difference between MERV 8 and MERV 11?
MERV 8 vs MERV 11 AIR FLOW Fine air particles are 2.5 microns and smaller. At that size, the air particles can get into lung tissue and enter the bloodstream. MERV 11 air filters can filter out a large percentage of fine particles, but a MERV 8 air filter can’t.
How long do FilterBuy filters last?
A general rule of thumb for pleated air filters (like ones made by FilterBuy) is to replace your filter every 90 days. As your filter traps more dirt, dust, and allergens from the air, filter efficiency decreases.
What is the difference between MERV 8 and MERV 12 filters?
The higher the MERV, the smaller the particles removed, and the more of them removed. MERV 8 filters are effective at removing most 3+ micron particles like lint, dust, most pollen and mold spores, dust mites and their debris. MERV 10 – MERV 12 filters remove most 1.0 to 3.0 micron particles plus bigger ones.
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.
Will MERV 11 hurt my furnace?
The short answer is that it can, but it’s not really an issue except under extreme circumstances. Most modern HVAC systems have no problem working with higher MERV filters, which is why millions of homeowners depend on them.
Are 4 inch or 1-inch furnace filters better?
Is a 5 inch furnace filter better than a 1-inch?
Replacing your standard one-inch air filter with a pleated 5-inch filter can result in better air quality inside your home. That’s because bigger air filters feature higher MERV ratings, leading to better filtration of pollutants and allergens.
Can a furnace filter be too thick?
When too dense of a filter is used in an HVAC system that doesn’t require that degree of resistance, it may restrict the needed airflow and make your furnace work harder. This will not only worsen its efficiency but may also lead to further damages.
What happens if you put an air filter in backwards?
By installing your filter backwards, air will have a harder time flowing through the filter and your air handler will have to work harder to make up for the loss of airflow. This could lead to higher utility bills and possibly damage your furnace or air conditioner.
