STEP 1 - Measure:

Firstly, you'll need to work out the type of grille you have. There are 5 common grilles types shown below. Match your setup to one of the pictures. Measuring your filter is easy once you have worked out the type of return air grille you have. 

Simply work out what side is D1 and what side is D2 and you can match your measurements to the large range of AirClean filters™ in the next step.

Type 1 and 2
Type 3
Type 5

STEP 2 - Match

Once the filter has been measured, you can match it to the correct size filter below. Use the column 1 and 2 to find the closest match. This can be 1-2mm different to your measurements without affecting the filter fitment.

If you find none that match, your still covered....we can custom order any size filter you require!
