Your product cost similar to other air purifies in my market area. But honestly with this article about the DIY being almost the same if not probably better than some might still buy your product. I had been thinking for a while about putting a filter on the highspeed fan with bought. Buy it is an impeller design and seems annoying lol. Thanks for an honest article. More companies should be so honest. I would probably buy more things online that way 😀
Does the size of the “commercial” purifiers contribute contribute to the cost/noise level? The blast looks much larger than the typical consumer air purifier. The improved performance:cost ratio could be (in small part) due to the relaxed marketing constraint on size. This is an obvious effect of good engineering: make the filter bigger!!
