Air purifiers are intended to filter the air rather than cool it. If you're looking to cool a room, you should consider an air purifier with a fan or air conditioning function.You can also get air purifiers that emit negatively charged ions into the air. When these ions combine with allergens or dust in the air, they become too heavy and will fall to the ground so you can clean it up with a vacuum cleaner. This helps to lower the risk posed by contagious diseases. It can also mitigate the symptoms of health conditions such as asthma and allergies like hay fever. An air ioniser is an alternative type of air purifier. Instead of using a fan or filter to purify the air, as is the case with most air purifiers, an air ioniser does it by electrically charging air molecules. If it's not possible to increase ventilation because your outdoor air quality is poor or you suffer from hay fever and open windows introduce pollen, then an air purifier could be a good investment.

Many models have air-quality sensors. If left on automatic mode, these machines will sniff out pollutants and spring into action as needed. If you've just sprayed deodorant, for example, it will detect a change in the air quality and work harder. Some have a night mode, which reduces the fan speed and dims any lights so that the machine doesn't keep you awake. If you're not planning to run your air purifier in the bedroom, you might not be too worried about this. You don't usually need to worry about air purifiers that use a HEPA filter alone to clean the air.
