Since there is not much room, my review is brief. I have congestive failure and the allergies and breathing issues I struggled through, sent me to the hospital with an exaserbated heart condition. The Lapotaire's evaluated the air quality in my home. I made the changes that they said had to be done. I can honestly say I don't think I would be here today without their help. I was that sick. I feel better than I have in years and my energy level is through the roof. I had been suffering with heart issues, post nasal drip and breathing and sleeping problems for years. Honestly, I no longer have allergies and everyone who comes by tells me how clean the air in my home smells. John and Lydia are true professionals and have the compassion to show people how to live healthy lives. If you have children with asthma and allergy issues, you owe it to them to take care of it.
