These are louder than expected with the emphasis the marketing puts on how quiet they are, but I used a 750 in a small bathroom (like 60 SQ ft if that) and it did prevent mold from growing. I can't speak to using it for spaces closer to the quoted square footage limit, but it definitely worked in a very observable way in the small space I have it in. I have others in larger spaces (still under their respective limits) where there wasn't such a big issue so whether or not they're doing the same job is less apparent. I used it to bathe while having to go without a bathroom fan in a small windowless (read: poorly ventilated) bathroom for weeks. Previously visible mold grew within 2 hrs of taking a bath. I cleaned the mold, plugged in the 750, and no mold grew at all during the following showers and baths. I haven't tried using the shower/tub without it since I'm not wanting to get up on a ladder if the bathroom fan that was installed doesn't cut it and mold does grow, but I do know that at least in this instance it has prevented the mold that literally popped up within hrs of taking a bath before having it running. I have mold poisoning and am very sensitive right now so this was a really pleasant surprise and an integral tool for me/my health. Pics of mold that hasn't been back attached.
I was so excited about this machine! I bought the smaller one for my small bedroom. It was working great! My allergies were non existent when in my bedroom and the room smelled fresh. Then it seems to have stopped working. It is no longer removing the typical stale bedroom odor and my allergies are back full force while in my room. I'm very disappointed as this machine seemed yo have so much potential.
With one on each of my three floor house, the level of comfort they provide is amazing. Plus, the freshness in our air is noticeable to everyone who visits us. This technology is truly remarkable.
My son who has allergic rhinitis has significantly decreased sneezing. I wanted to purchase another one for his bedroom but it was no longer on sale. When will you have another 20% off?
I am an asthmatic and had been experiencing an uptick in my need for a rescue inhaler this Spring, aling with sinus problems. I ordered one for the bed room and it did so well in curbing symptons i ordered another for living-room and family room. Thanks for a good product!
