Finding the Perfect Fit No matter the size, we’ve got you covered

Green Means Clean Refreshing new look, same great quality
Our new, green frames are constructed with the same high quality materials that you have grown accustomed to.

When you see Filterbuy green, you can exhale with the confidence that you are breathing crisp, pure, fresh air.

Pre-filter A (HRF-A100) activated carbon (charcoal) replacements complement your Honeywell R HEPA air purifier filter by extending its lifespan and trapping more harmful particles
The porous design creates a large surface area that adsorbs more pollutants and enables odor elimination, protecting homes from pets, smoke, gas, and other adverse smells
High quality coconut shell fiber media uses a thicker material that captures more contaminants without impacting air flow (replace every 90 days for best performance)
Easy installation pre-cut filters use industrial grade components that are 100% manufactured in the United States and designed with recyclable materials
Compatible Models: Honeywell HPA094, HPA100, HPA101, HPA104, HPA105, HPA106, HPA3100, HPA5100, and HPA5150

These are great
These are awesome pre-filters. They are cut to size and fit perfectly in my air purifier. I don’t know how well they collect dust and allergens, but I haven’t noticed an increase in dust in my room or my allergies flare up, so I think they work. I recommend them!

Good replacement filter for your Honeywell.
Nice filters. Fits my Honeywell air purifier just like the original. No complaints here.
