Hi, Harvey. I'm sending back a hello " Rruff" to you, And hope your bed's near a HRV system too. My husband suffers from Asthma as well. HRV's help with cats hair, and with doggie smell! Yes frankly,  Asthma does really "suck", But HRV's filters deal with the dust mites and 'muck'. So New Zealand, ..... what we can do, Is,  YOU  ALL GO AND GET A HRV TOO!

Since we bought our place winters had been hard with build up of condensation on the ranch sliders. There would be tears and big puddles every morning during the winter months. It was that bad the build up of moisture in the house we would get mold on clothing in the bottom draws, shoes in the wardrobe and on the bottom of the curtains. We installed a heat pump when we moved in but that had no affect on the moisture build up. We had hear of HRV and thought how can it work during the winter months when there is very little heat in the day to heat the roof. . . But I got to eat my words. The moment it was fitted and turned on you could taste the cleaner, dryer air in the house and winter came around and the house has stayed dry ever since we had the system fitted. Cleaner, Dryer and Warmer air has made a big difference to our health and life. Even in the winter months A Bonus it will cool the house down during the hot muggy summer nights

We have five people, two dogs and a cat in our house - and everyone had asthma and allergies, from mild to severe. We had the HRV installed a few years ago, and the changes are unbelievable! The asthma is gone - I mean gone completely. The allergies we had are virtually gone. We hardly ever see the doctor now, and our house smells great. It has made a huge difference to us. Thanks HRV you rock!

I have had my HRV installed for 2 years now, I love it! I used to be like the lady on the ad that spent and hour every morning with the squegee and towel cleaning all the water off my windows! I used to get 1/2 a teacup of water off my sons window and now I get an extra hours sleep in, because I've never wiped a window since! And the damp musky smell in my bathroom, now gone! Thanks HRV!
