Run an Air Purifier
The amount of time that an air purifier should be running will depend on its capacity and the size of the room. Generally, air purifiers are designed to clean a certain number of square feet of air per hour. You can find out how many square feet a particular air purifier can clean in under 60 minutes by looking at the manufacturer’s recommendations. If you have a large room, run the unit for at least two hours.
When you first install an air purifier, it should be placed in a well-ventilated room or near the bedroom. You also want to make sure that there are no obstructions to the air vents. The air purifier should also be situated at least a foot away from any furniture and walls in the room. This way, it will allow the air to circulate properly. When you first install an air purifier, you should follow the manufacturer’s instructions and set up the machine properly.
Once you have chosen a room and a particular model, you should calculate the extraction rate of the air purifier. This measurement will help you find out the amount of air that the machine will clean in an hour. Typically, a device with an extraction rate of two air changes per hour is good enough for a room of between one to three square feet. However, if you have a larger room or a small one, you might want to consider a model with a higher extraction rate.
How Long Should You Run an Air Purifier?
Most air purifiers use very little electricity. Their electrical power draw is about a half a watt or less for a standby/off mode. A purifier running at high speeds will use about 45 or 55 watts. You won’t notice any difference in your energy bill if you run an air purifier 24 hours a day. A high-efficiency model will save you money by reducing your energy bill to about six to ten cents per kWh.
Depending on the model and the air quality, a good air purifier can clean your indoor air for up to 8 hours per day. The air purifier can also help with seasonal allergies, as the air inside the home can have five times the amount of contaminants found outdoors. If you leave the air purifier running, it can leave your home polluted. This is why it’s recommended to run an air purifier for 24 hours a day if possible.
The best time to run an air purifier is whenever you are home. However, the device should not run continuously when you’re not around. Even if you’re not at home, your air purifier will still clean the air for you. You don’t want to leave it on all night long and end up with dirty air. It is better to leave it on for a couple of hours to let the purifier do its job.
