+1 (978) 295-7538A5FMP911-8 pre-filters, 8 per pack
The pre-filter is the first layer in the AllerAir AirMedic Pro 5 MG and AllerAir AirMedic Pro 5 Ultra and the one you replace most often. It catches dust, hair and lint at the intake so the HEPA and the carbon bed behind it never see coarse debris. Skipping it does not save money. It moves the wear onto the carbon and HEPA stages, which are the expensive parts of the machine.
How often should the pre-filter be changed?
AllerAir recommends every two to three months, and more often where there are pets, carpet, construction dust or heavy foot traffic. They are sold in packs because the interval is short.
Why the cheapest filter matters most
- 8 filters per pack — roughly twenty months of changes at the recommended interval
- Protects the HEPA — coarse dust caught here never reaches the pleats downstream
- Protects the carbon — a dust-blinded carbon face stops adsorbing long before the bed is spent
- Keeps airflow up — a loaded intake filter drops the delivered clean air of the whole machine
- Tool-free change — no disassembly
Service notes
Change the pre-filter at every carbon change as a matter of course, and on the two-to-three month cycle in between. Keeping to it is the cheapest way to protect the carbon and HEPA stages.
