Everything you need to bring your Airpura 900 MAX back to peak suction and odor control. This bundle replaces both MERV-13 particle filters, both 20-lb carbon canisters (40 lb total), and includes four prefilters so you have an extra set for the next service. Top-access design makes changeouts fast.

2. Unlatch four top latches; lift off the top and the foam gasket.

FAQs

Why are there four pre-filters?
The 900 MAX uses two pre-filters per change. This bundle includes two complete prefilter changeouts (4 pcs total), so you’re ready for the next service.

How often will I need this bundle?
Intervals vary by load. Replace the pre-filter/MERV-13 when suction drops, and replace the carbon when off-gassing/odors return. Heavy contamination may require a change within weeks.

Any special cautions?
Yes, do not use the unit in flammable atmospheres; keep humidity ≤50%; and make sure the unit is OFF before plugging in to prevent motor issues.
