1.Which is better HEPA or non HEPA filter?
⑴.Depending on the usage scenario, HEPA filters are mainly used to filter small molecule particle dust and various suspended solids with a diameter of more than 0.3 μm, while ordinary filters mainly filter 5 μm or more (primary-efficiency air filter) or 1-5 μm (medium-efficiency air filter). air filter) particles of dust and suspended solids. For example, the diameter of PM2.5 is less than 2.5 microns, so HEPA filters can do it.In short, the HEPA filter has a higher filtration level.
⑵.In fact, the essential difference between HEPA filters and ordinary filters lies in the filter material. The most common materials for HEPA filters are five categories: chemical fiber PP filter material, composite PET filter material, melt-blown filter material, polyester non-woven fabric and melt-blown composite filter material. materials, glass fiber filter materials; five types of HEPA filters of different materials each have their own advantages and disadvantages, and their main application fields are also different. Among them, HEPA filters made of composite filter materials are acid and alkali resistant, corrosion resistant, and have high melting points. , stable performance, non-toxic, odorless, evenly distributed, low resistance, high strength and environmental protection, it is the most widely used in air purifiers.The filter screen of non HEPA filter is mainly composed of non-woven filter cotton, fluffy cotton, glass fiber cotton, corrugated aluminum mesh, nylon mesh,Lacquer mat,304 stainless steel wire mesh,Composite filter material etc.
2.What is the average lifespan of a HEPA filter?
It is generally recommended to replace the HEPA filter regularly every ten years. EM is assessing whether filter replacement is typically determined by the lifetime of the filters or other characteristics.
3.Does HEPA filter improve indoor air quality?
HEPA air cleaners with sufficient CADR can reduce concentrations of indoor PM2.5 (the smaller particles) by an average of 50% or higher.
4.Where is the best place to put an air purifier?
Living room air purifiers should be a medium between the middle of the room and near seating areas. The middle of the room is the best spot for an air purifier to handle air pollution, because it both has access to the most particles and can have the biggest impact on moving air in the room.
