SUBSCRIBE to This Old House: http://bit.ly/SubscribeThisOldHouse Up in the loft, Richard showed Kevin why it's important to regularly change air filters in a forced-air HVAC system. Richard recommended making sure to get the right size and to select a "pleated" filter, which is better than a non-pleated one that you can see through. Richard also showed a "reusable" filter that can be cleaned and reinstalled. Finally, Richard showed an "electronic" air cleaner that causes dust to stick to plates that can be cleaned by rinsing with water. Electrostatic pleated air filters are available at most home centers and hardware stores. Many of the filters Richard presented are manufactured by 3M Filtrete [https://bit.ly/2UwWfVt]. Professionally-installed electronic air cleaners are available through HVAC contractors. The model Richard displayed is manufactured by Trane [https://www.trane.com/index.html]. Additional assistance was provided by Air Purchases, Inc.
