Air Purifiers for coverage area from 100 to 250 sq ft. Choose the right purifier for your small spaces like cars, bathrooms, nurseries, closets, and more. What size room (sqft - square feet) are you looking for your air purifier to clean? Those who know the air purifier industry know that there typically is not one singular product that is superior to the next.  There are many variables involved when buying an air purifier such as how big is the desired coverage area. It's important to know the estimated area of the room (s) that you want to purify.  Otherwise, one could easily buy a product that is not adequate for a particular room size, or they could end up paying too much on a unit that is better suited for industrial use, rather than personal. Our online store assists customers in finding the best air purifier to fit their needs. This category of custom air purifiers will prove to be the best option in finding a purifier to clean the air in a particular environment.

Example: 10 ft x 10 ft = 100 sqft room size Note: If you place an air purifier into a room size that is less than what the air purifier is certified for, the air purifier will purify the air at a faster rate. On the other hand, if you place the air purifier into a room size that is greater than what the air purifier is certified for, the air purifier will still purify the air, but at a lesser rate and will not be as effective as the first scenario. Best case scenario is that the room that you put the air purifier into is no more than 67% of the size of room the air purifier is certified to clean effectively. Example: You purchase an air purifier that is certified for up to 1000 sqft. The room you put the air purifier into should be no larger than 670 sqft for maximum effectiveness in cleaning the air in the room. You will get more Air Changes Per Hour (ACH) out of your air purifier using this method. Tip:  You should not consider a unit that delivers less than 2 air changes per an hour.  

In fact, most people who suffer from allergies perfer 5 or more air changes an hour. CFM (Cubic Feet Per Minute) x 60 (Minutes per Hour) Example:  Each unit wil list the CFMs that it delivers.  Let's say it is 200 CFM on the unit you are looking to buy and the room is your bedroom which is 10 by 12 by 8.Category: Water - Gas Purification ALT carries the most diverse inventory of used water and gas purification systems. homedics air purifiers reviewsWe carry systems from leading manufacturers, including Mettler Toledo, Biotage, Thermo Scientific, and Millipore to name a few. air duct cleaning reno nvAll of our used lab equipment is fully serviced prior to shipping and comes with our industry leading warranty.fellowes cd dvd lens cleaner
