Think Crucial Replacement Hood Filters Compatible With Nutone Part #ACCGSFHP2, 1-Year Supply Style Pre Filter Kit Parts -Models: HF 1.0, HF 2.0, HF 3.0, HF 3.1, HR 2.5 and HR 2.6 (1 Pack)

This part looks quality and fits exactly in my Venmar HEPA 2000 whole house air filter system.

Fits my air exchanger perfectly. Shipment was fast. Best price I could find for this filter anywhere

I haven't installed it yet, but comparing to an official Broan Nutone hepa filter, it is easy to determine that both the main filter and the prefilter are less restrictive to airflow, and therefore less filtering is occurring, and therefore it confirms that this product is not a true hepa filter. This can be determined just by looking at the Prefilter compared to original prefilter, and by blowing air through the main filter and comparing flow rate to the that of the official hepa filter (both brand new).The upside, however, is great price, around 1/3 to 1/4 of the current price of an official filter, increased air velocity, less load on the fan motor, and decreased CO2 level if your system brings in outside air, since you will have a bit higher flow rate.It's too bad, however, they didn't cut corners, and used the proper hepa filter material, then it would be more expensive but I would give 5 stars.

Works great with my Broan Nutone air circulation system

Perfect Replacement for the overpriced Broan filters

Good replacement combo filters. Also can be used with the Broan whole house air exchanger...just check part numbers before ordering.

fits

We will definitely buy again. Fit was perfect and it arrived on time
