It's a big job for a big room, but cleaning carpets/upholstery then spraying this on them appears to have made a big difference in how the air in the room feels to a person who is allergic to dust mites. Buying a large sprayer would probably be worth it since reapplication is necessary every few months.

I love this product. It is very easy to use. It can be mixed into a spray or added to a steam cleaner. There is A LOT of product here so it will last a while.
