Changing your filters improves your home air quality. But time flies, and it's easy to forget. With this program, a filter will show up at your house every three months to remind you it's time. All you have to do is change the filter.

Bob’s Heating offers a 4″ Pleated Media Filter. This filter is rated 20 to 30 times more effective than 1″ spun fiberglass filters, and can remove even microscopic particles. This provides personal protection, as well as improved furnace efficiency and economy, and can even protect home furnishings and attachments.

With the enhanced performance of the Pleated Media Filter, it is critical that filters be changed regularly, normally at 90-day intervals. The average 1″ spun fiberglass filters should be changed every 30 days. Failing to change filters can reduce airflow and may result in damage to your furnace.

Our 1-Year and 3-Year Automatic Filter Replacement Programs include a pleated media filter delivered to your door via USPS every 90 days. We offer six different filter sizes; please be sure to indicate the model number that matches your system.
