Time to refresh your Blue Pure 411i Max or 411a Max air purifier?
This 2-pack of upgraded mixed carbon filters is exactly what you need.
They're designed to be a perfect fit for your model (compatible with part # F4MAX), so installation is a total snap.
The 'upgraded' part means they have a special mixed carbon layer that's super effective at trapping and neutralizing household odors – think cooking smells, pet odors, or lingering smoke – leaving your room's air feeling fresher and cleaner.
Buying in a 2-pack is a smart move: it saves you money and means you've got a spare ready to go.
Each filter should last a good 6-9 months with normal use, but that depends on your air quality.
When it's time to swap it out, you'll notice.
Keep your purifier running at its best and breathe easier with these reliable, high-performance replacement filters.
Simple maintenance for cleaner air!
