Product Description PREFILTER (F1) FOR IQAIR HEALTHPRO 150 MODELS Shows as "F1" on Healthpro 150 unit display panel The IQAir PreMax MG (Multi-Gas) Filter is a dual purpose filter which contains: 1.9 square metres of wet laid non-woven glass microfibre, mini-pleated 1kg of granular activated carbon blended with ChemiSorber - a chemical adsorption media. The IQAir PreMax MultiGas Filter is usually shipped with the IQAir HealthPro 150, however owners of the HealthPro 100 (previously known as The Allergen) can use the PreMax MultiGas filter instead of the standard PreMax Filter. Doing so however, alters the life span data for the HealthPro 100 units and decreases its coverage area from 95m2 to 65m2. Shelf Life Under normal indoor storage conditions the particle filters (i.e., PreMax and HyperHEPA Filters) have a virtually unlimited shelf life. Under normal indoor storage conditions and if boxes remain unopened, the V5-Cell Gas & Odour Filter will also remain usable for at least 5 years.
