What is the MERV rating for Purafilter 2000?
MERV 8
The media is designed to perform as a MERV 8. MERV 8 filter performance delivers the right balance between reduction in airborne particles and good air flow preventing any strains on your system s motor. Lasts up to 3 months. For best results change every 3 months.
How are home air filters rated?
Air filters are rated according to their Minimum Efficiency Reporting Value (MERV). Created by the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE), it’s a porousness scale that goes from 1 to 16, with most home air filters ranging from 4 to 13 MERV.
What MERV stops mold?
MERV Rating A rating between 1 and 4 will protect your HVAC system, but will not improve air quality. A rating between 5 and 13 is useful in fighting mold, pet dander, bacteria, and some viruses. Anything rated at a 14 or higher has the highest efficiency.
How do I know what size air filter I need?
Check the old air filter for its size The first (and easiest) way to figure out your furnace filter’s size is to check your old air filter for its size. Most air filters have their size printed on the side of the frame. The length, width, and depth of the filter are measured in inches.
What are standard air filter sizes?
Here are some of the most common furnace and AC filter sizes:
- 10 X 20 X 1”
- 14 X 20 X 1”
- 16 X 24 X 1”
- 18 X 30 X 1”
- 20 x 20 x 1.

What happens if you put air filter in backwards?
When a furnace filter is placed backwards, the fibers can’t do their job properly. This means your furnace has to work harder to generate the same air flow, resulting in increased energy costs. Particles are also allowed to build up irregularly, making the furnace working even harder to draw air.
