We recently purchased a Micro Power Guard air cleaner through Vredevoogd Heating and Cooling. Brad, the sales representative, gave us information on the product and we decided to purchase it because of a family history of allergies and asthma. We also have a dog and therefore, our house didn’t smell as fresh as we would have liked. After purchasing the product, our house has a fresher and cleaner smell to it. I believe there is less dust too. One of the big things we have noticed however is that our kids have been staying pretty healthy which is a big feat with all of the flu bugs going around. We have been really pleased with the Micro Power Guard sir cleaner and are glad we purchased this product.
