Practical Pleat 5" Filter for 1" Return Grille - MERV 11 (2 Pack)
Regular price
$129.76
Practical Pleat filters are 5" thick pleated filters designed to fit in your 1" return grille, with no modifications to the grille required. Remove your old filter and slide the Practical Pleat into place!
Practical Pleat filters have 433% more surface area and 28X increased filtering efficiency over typical 1" return grille filters. They allow you to have better longer lasting filtration without increasing strain on your equipment, and the foam gasket prevents dust from bypassing the edges of the filter!
2 Pack, choose your size in the dropdown menu above.
Low Pressure Drop
- The Practical Pleat's large surface area means low resistance to airflow, and low pressure drop when the blower motor starts and runs, as compared to the resistance of a pleated 1" filter. This means better filtration without more strain on your equipment!
- Initial Resistance .09 in W.G @ 1180 cfm's.
- Less strain on the fan motor means potentially less energy usage versus a 1" pleated filter.
Reduces Air Noise
- Less resistance to airflow reduces noise at the air intake.
Gasket Eliminates Filter Bypass
- Foam gasket provides a seal between the filter and return grille, preventing dust from bypassing the filter.
- Each Practical Pleat lasts up to 6 operating months.
MERV 11 Filtering Efficiency
- Removes smaller particles from the air than standard fiberglass and lower MERV 8 rated filters that are typically used in return grilles.
Particle sizes filtered by the MERV 11 Practical Pleat:
0.3 to 1.0 Micron - 32% per cycle*
- airborne pathogens like smallpox virus, meningitis bacteria, tuberculosis bacteria, anthrax bacteria, bronchitis bacteria, etc
1.0 to 3.0 Microns - 69% per cycle*
- larger airborne pathogens like bacillus anthracis, mycobacterium, airborne mold spores, fungi, etc
3.0 to 10.0 Microns - 87% per cycle*
- allergens like skin dust, bed bug feces, pollen, dust mites, animal dander, etc
* Independant Laboratory Test - ASHRAE 52.2
How to measure - Choose the same size Practical Pleat as your current filter. If you have a 20x20x1 filter, select the 20x20x5 Practical Pleat. If you don't know what size filter your grille takes, measure the area of the grille where the filter rests within. Practical Pleat filters are undercut by 1/4" on all dimensions as is standard for filter sizing so that they fit in the grille framing properly, unless noted as "Exact L x W" next to the size in the dropdown menu, then it is made to the exact face dimensions, but the thickness remains undercut. Make sure you have 5" of space behind the grille for the Practical Pleat to slide in all the way, and there are no studs or obstacles blocking the way. There are 2" Practical Pleats available on our site if there is not enough room for the 5".
