My husband who is immunosuppressed and has developed asthma since his kidney transplant used to get at least one bout of bronchitis every winter.  Since we installed the HRV about 4 years ago he hasn't had a single dose of bronchitis or any other complication of a cold.

After many discussions over whether or not to get an HRV system we finally bit the bullet and it has honestly been the best decision ever!! With two little girls and a husband with asthma no longer do I have to lye awake waiting for the wheeze and worry during winter months, inside the house they are no longer wheezy! Every house should have one, thanks for our healthier home HRV.

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!

My HRV has taken away  the condensation and dampness away from my home. Our house always has dry air inside, even when it is raining.  Our son who has asthma  aged, hasn't had a asthma attack since we had it installed. His constant running nose that he has in the winter months stops as soon as he comes inside.  This tells us the HRV really  works. We will never live in a house without one again.

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 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 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.
