A Look at Air Purifier Manufacturers
Honeywell dates back to 1885, and produces thermostats, air cleaners, humidifiers, and more. They offer four types of air filters: Replacement Media filters, HEPA air cleaners, Media Air Cleaners, and Electronic air cleaners. These filters contain an AIRWATCH indicator, which reminds when to change filter, and come with a one-year warranty.
There are many different kinds of air filters available today, such as HEPA, standard, pleated, electrostatic and electronic filters. They should be changed once a month. Pleated Air Filters catch around 35% to 40% of the particles in the air. The cost of these filters ranges from $5 to $20 which is slightly more than that of standard filters.
The air is required to be pure and without dust in places like research laboratories where even a dust of 1ppm or 1 part per million could contaminate the environment and would cause a lot of effect in the research recordings. I don’t plan to go into complicated details, but an overall understanding of air purification technology is good to have, especially if you are planning to buy home air purifiers but don’t know which one to choose. House air filters are very necessary in hospitals where patients suffering from wheezing and asthma have to be in a very pure environment free of dust, else their problem could aggravate. The internal combustion engine uses filters like paper or cotton.
The popular ones out of these and which can be used to remove air pollutants from air conditioners are the standard, pleated and electrostatic filters. You will find these filters situated in walls, ceilings, furnaces, or right in the air conditioner. Because of their greater surface area with filter material folded back and forth like a paper fan, manufacturers assert that these filters can last between two to four months.
