If your home is too dry, will you buy a humidifier? You need to know when you should buy the humidifier for your home. While some areas have been getting more moisture than they know what to do with, the colder months can be a time when dry air affects some people with allergies or sensitive skin conditions. If this is the case, a humidifier is a device that transforms water into mist or very tiny droplets to disperse in a room to help increase the humidity level. Evaporative humidifiers work by evaporating water inside the humidifier which sends water vapour into the air, while non evaporative (or ultrasonic) humidifiers transmit moisture to the air in a visible or perceptible form without the need for a fan. Here are the common types of humidifiers you're likely to find in stores. . Warm mist humidifiers (evaporative) heat water to a boil and emit the steam to release moisture into the air. Some types use mineral filters that trap water deposits, and these filters need changing. . Cool mist humidifiers (evaporative) use a fan to blow air over a wet wick and move the humid air into the room. . Ultrasonic humidifiers (non evaporative) use a vibrating diaphragm to convert water into a vapour. While a fan isn't required, some units do include a small fan to increase the spread of vapour throughout the room. Humidifiers come in various sizes and prices. Before buying one, you need to figure out the size you need by measuring the dimensions of the room it'll be in (whether this is a bedroom or the living room, for example). For sleeping areas, ultrasonic models are said to be quieter than evaporative ones. You should also choose a humidifier that's easy to maintain and clean and make sure you drain, rinse and dry it every day. Always follow the manufacturer's instructions with disinfecting and cleaning your humidifier and any residue build-up to make sure the moisture the machine emits is safe to breathe.

A top level air purifier should always equip with a HEPA filter. HEPA stands for High Efficiency Particulate Arrestance or High Efficiency Particulate Air. The key element for a HEPA filter is usually composed of an ultra-fine and glass-fiber material, which has to pass a filtration test to be certified as HEPA. Specifically, the United States Department of Energy (DOE) standard for HEPA filters requires a minimum 99.97 percent filtration of particles 0.3 microns in diameter. To differ from USA, the European Union has its own standard, EN 1822:2009, for HEPA certification. With this standard, HEPA filter is divided into several classes with filtration efficiencies ranging from 85% to nearly 100% for 0.3 μm sized particles. For most of filter, 0.3 μm sized particles are tough to be blocked, but HEPA filter would be able to remove over 99.97% of some types of particles that is smaller than 0.3 μm in the air. HEPA filters can block great amount of particulate matter that cause or aggravate asthma and allergies including:dust, pollen, soot, pet dander, dust mites, mold spores. HEPA filters can also make significant contribution on the reduction in spread of Covid-19. To learn more about HEPA filter with Top Rated Air Purifiers, please click here.
