Payment, delivery and returns all happen at checkout, away from this catalogue. Figures shown are from our last update; see how we keep this current.
The MR5866 runs two filters simultaneously through side intakes, so its genuine cores ship in pairs. Original covers daily dust, pollen and household odours. Enhanced, in light grey, adds a heavier carbon coat. Pet dander stacks a fourth high efficiency stage for animal homes. Multifunctional carries a gas phase media that works like a specialist against odours and fumes.
Every version captures up to 99.97 percent of particles at 0.3 microns through the HEPA stage, and every pair is cut to the exact frame the MR5866 seals against. When the filter light wakes up, change both sides at once: the machine breathes evenly and the media wears out together.

Original is best
I bought generic filters because they were cheaper. Well, they sucked! The genuine filters are always the best option. From now on I will pay more for original quality. They get the job done. Don't cheap out on your air purifier filters.
Cynthia Rostad · December 19, 2025 · verifiedFits Fine, quality of filtration unknown.
Perfect fit, value for dollar vs. OEM part. I can't speak to the actual air quality or air cleanliness; would love to have that info if anyone has reliable testing data.
