Are your air filters facing the right way? It’s a simple yet vital question for optimal indoor air quality. We’ll delve into the correct orientation for air filters, including: MVHR, Panel Filters, Bag Filters, and HEPA filters.
MVHR Filters
Wire frame MVHR filters are inserted with the tag hanging out, allowing easy removal. G2, G3 and G4 filters are multidirectional. M5 filters are a progressive media, featuring distinct sides. The fluffy side stops large particles like dust, while the flat side captures smaller ones like pollen. M5 filters are designed to protect the dense side from large particles, making correct orientation crucial for optimal performance.
Panel Filters
Panel filters are designed for one-way air flow, with dirty air passing through one side and clean air exiting the other. Typically, stickers on panel filters indicate dimensions and airflow direction. In the absence of a sticker, determining the correct orientation is possible. Pleated panel filters have metal mesh on the clean air side, while fibreglass filters have the coloured side facing dirty air and the white side facing clean air.
Bag Filters
Bag filters, similar to panel filters, facilitate one-way air flow. Stickers on bag filters typically indicate dimensions and airflow direction. In their absence, determining orientation is possible. Firstly, the pockets of bag filters must open towards the dirty air side to capture particles. Next, when installed perpendicular to the floor, the pockets should align vertically. However, if installed parallel to the floor, pocket orientation doesn’t matter as long as they open towards the dirty side.
HEPA Filters
HEPA filters allow allow multi directional airflow and should be installed with the seal facing the dirty air. Align pleated paper rows vertically when installed perpendicular to the floor. Deep pleat HEPA filters should not be installed parallel to the floor.
In Summary…
Understanding proper placement ensures optimal filtration performance. Stickers on filters aid identification, but other methods exist for orientation determination. For various filters, specific guidelines apply, such as aligning pleats and avoiding parallel installations. Mastering the right orientation ensures improved indoor air quality and filter efficiency.
