Our son spent a week in hospital when he was 3 weeks old due to 2 collapsed lungs. His lungs were then very  weak. Our house is 90 years old and over winter was always damp. Our son had to go to hospital each winter due to the damp, cold air. So, we got an HRV installed. Now our son has not had to go to hospital in the last  3 years! Not only that, our home is easier to heat and the air is dry.

We had our HRV system installed April 2009. We have noticed a complete change in the dynamics of our house. Winter is not such a daunting time and we find on winter days that the HRV supplies us with a good base and has made our home very easy to heat. We would strongly recommend the HRV to anyone, especially if you have anyone in the home with allergies or like my daughter suffers from asthma.

We had HRV installed in our home in Glenfield which was cold and damp and was making our then 18 month old daughter sick. We were extremely happy with the immediate improvement in her health. 3 years later when we sold our house we knew that we would have to factor in the cost of installing HRV into our new home. We were fortunate when we found a new house that it had HRV so still no asthma here.

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!

I have not had to wipe down a window since I had the HRV installed.  The condensation and damp feel is gone.  I have also not had an asthma attack since I had it put in so this tells me it is working.  The clothes in my cupboard are dry and mould free even right in the very back!!! Love it

I am a 50 year old woman, and have all sorts of allergy problems within my family. I suffered with hayfever, and eczema for as long as I can remember, but then one day I was having breathing problems, and my chest was very sore, so I went to my doctor, and he sent me for a blood test for allergies. The result came back that I had asthma, which was sort of a surprise, but not so much.

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!
