Compare Air Purifiers
The air around us is filled with impurities such as smoke, chemical fumes, pollen, odors, dust particles and microorganisms. These may result in allergies and respiratory disorders, among other illnesses.
Air purifiers help cleanse the air of most of these harmful substances. These devices filter out the impurities to release fresh, clean air into the atmosphere. Since there are several different types of air purifiers available in the market, choosing the right one becomes difficult. Comparing different purifiers before making the purchase is always a good practice.
There are several factors that can be considered when comparing the different types of air purifiers. The size of the room, the amount of pollutants present, the level of purification required and the running cost should be considered.
HEPA air purifiers are the most basic air filters. Since they use a cloth type filter, they can only eliminate solid particles and not gaseous substances and odors. On the other hand, ozone based purifiers prove effective against bacteria, odors and most gases but can do little to prevent allergens and dust particles. The ionic air purifier is effective against most impurities except odors.
The noise emitted by the air purifiers should also be considered. A constant buzzing or humming sound can be distracting and even annoying in an environment that requires silence such as an office or a bedroom. Ionic air purifiers are usually the most quiet filter systems available.
For eliminating germs, bacteria and other microorganisms from the air, the ultraviolet light air purifiers prove most effective. UV light is known to sterilize and even kill many disease-carrying germs. Hence, these purifiers are popular in hospitals.
Each type of air purifier has its own pros and cons. While some filter out dust and other particles, others eliminate odors and harmful gases. The prices of the purifiers also vary greatly depending on the purification system and the cubic capacity of the purifier.
