Review on VEVA Air Purifier Filter Replacement - High-Quality HEPA Filters, 3 Pack with 4 Precut Activated Carbon Pre-Filters, Compatible with Honeywell HPA300 Purifiers & Replacement Filter R by Elvis Kimbro

Good. The replacement main filters are almost identical to OEM Honeywell. I haven't noticed any smell or issues with them and they are cheaper. I would give the product 5 stars. Bad pre-filter. This is the second batch of non-OEM pre-filters I have received. Although they are pre-cut to size, they are a thicker unknown material and if you ask me impede airflow to the device. I could literally make a video showing how the car sounds with this pre-filter compared to the OEM pre-filter. It sounds and feels like the car is working hard with this pre-filter. I find it was cheaper to buy 3 filters with a pre filter than just 3 filters. I go back to the Honeywell pre-filter. You'll have to cut it out, but I can use scissors. Honeywell/Kaz America is their own worst enemy. They sell you a unit and then try to trick replacement filters out of you, giving these non-OEM vendors the opportunity to succeed. I have no problems with the filters, the pre-filter needs to be replaced. I use b4 again.
