Absolute value for money! – Initially had reservations about the name "Kleva" brand,... we own an Austin Air Health Mate unit which cost $1,000 roughly 25 years ago and purchased Samsung and Aldi units about 2 years ago. We purchased the Kleva unit, due to the need for something in addition, to the older units,....an excellent price and features, super quiet and great air output, we bought it based on the fact, that we went on holidays recently, one of your units was installed at the place we stayed at. The Remedical unit was exceptional!, we wouldn't hesitate to recommend it, it's equal to/if not superior to "Name Brands", my wife suffers with sensitivity to fragrances, perfumes, detergents, fabric softeners, etc,etc. It made a huge difference, as the place was full of carpet, and bedding full of "Clean Products". We took the Aldi unit with us, handy, a bit effective but not in the same league as yours!.... at least 3 times the air movement.
