Why Your HVAC System Needs Smart Filters
Remembering to replace the filters in your HVAC system can be more difficult than it seems. In addition to regularly replacing filters according to the manufacturer’s instructions, you may need to change filters more often if there is an environmental factor that clogs them more quickly. But knowing when to change your filters or keeping track of when your filter was last changed can sometimes escape your attention. Smart filters for your HVAC system can remind you when they need to be replaced, so it’s one less thing you have to keep an eye on.
Why you need to change HVAC filters
A filter is designed to remove particles from the air stream that your HVAC system draws into your home for heating and cooling; Over time, these particles become stuck in the air filter. They will ultimately make it harder for your HVAC system to move air through it, causing the fan to work harder. This can make your entire system less efficient, which will increase your energy bills, and can also shorten the life of your HVAC fan motor as it gets hotter and causes more wear and tear.
Why you need to change filters in advance
Most manufacturers recommend replacing your HVAC filter at least every 90 days, but to ensure the best air quality, some recommend changing filters every 30 days. If you live in an area with a lot of pollen, you may need to change the filter seasonally to keep up with the extra particles; If you live in an area that experiences wildfire smoke or heavy smog, you may need to replace filters after smoke to keep your system running smoothly. Another common reason to change your air filter more often is if you have been doing construction work in your home that is causing excess dust. These particles can clog the filter faster than under normal circumstances.
What is a smart HVAC filter?
Smart HVAC filters have a sensor that reads the air pressure in your HVAC system, detecting the drop in pressure as air flows through the filter. The more debris and particles the filter catches, the lower the air pressure will be on the side of the filter opposite the fan. A smart air filter will monitor air movement past your filter and use an algorithm to determine when it’s time to replace the filter. Smart filters for your HVAC system will send a signal via an app to your phone or tablet to alert you when it’s time to replace the filter, and in some cases can monitor air flow and tell you a schedule for how long the filter will last.
Where to find a smart air filter
There are currently two types of smart air filters available. One system from Filtrete connects to your phone via Bluetooth to send notifications about your air filter. This system can predict how long your air filter will last and also notify you when it’s time to replace it. The downside to this system is that it doesn’t work with Google Home or Alexa, so to use it you’ll need a separate app, which can be downloaded from Google Play and the Apple Store . Another smart filtration system available is from Woosh ; This system is designed to pair with your existing smart thermostat through an app that you can download from Google Play and the Apple Store . The Woosh system will also automatically order a replacement filter element for you when your current filter requires replacement. Of the two systems, Woosh has a higher initial cost at $149, but then costs $22 to replace each filter element. Filtrete has a lower initial cost, ranging from $25 to $35 for two filters and a smart device that attaches to the surface of the filter. However, if your goal is to create less waste, the Woosh system uses a frame that is designed to last longer, with smaller filter inserts and creates less waste, while the Filtrete system requires replacing the entire filter, leaving only a smart device that connects to it.
