Indoor Air Purifier
If you do not yet have an air purifier, here are some factors to consider when making your selection. If you are unsure which system will be best for your home, our qualified HVAC technicians will be happy to offer their professional advice.
Choose the right size for the room
It is important to select an air purifier that will be able to properly clean the area it is placed in. Buying a large air purifier and running it on a low setting is highly preferable to running a small purifier on a high setting, because the smaller device will use much more energy.
The best air purifiers will trap a high amount of particulates in one cycle of air. We recommend selecting a purifier that traps well over 90% of particles in one single exchange. Most air purifier brands will list this percentage on the packaging; if the percentage is not listed at all, it is probably very low. Additionally, in order to have truly clean air, an air purifier should be able to exchange a room’s air several times per hour (we recommend at least 5 times).
An ideal purifier both removes a high percentage of particles and has strong air flow. This combination is often referred to as the Clean Air Delivery Rate, or CADR. The higher the CADR rating, the faster the air purifier will clean the air.
Filter Change Indicator Lights
A filter change indicator light is extremely useful in alerting you when it’s time to change your filter. If you cannot remember the last time the filter was changed, you can simply check the device itself.
