A new Wi-Fi-enabled HVAC market thermostat can let you know when air filters should be replaced.

The Filterscan, from CleanAlert, notifies HVAC construction contractors, building owners and consumers when an air filter needs changing.

The unit can send an alert to a smartphone, tablet or computer.

“We know that a clogged air filter is the primary cause of HVAC equipment failure and that eight of every 10 filters are not changed at the appropriate time," said Terry L. Reavis, the vice president of sales and marketing for CleanAlert. “The question of when to service an air filter has vexed contractors and building managers for years and many users have resorted to servicing their filters according to a schedule. Unfortunately this approach can lead to lost revenue and unnecessary material costs when filters are serviced too often.”
