Marketed as:
Filtrete is endemic past 3M, a large consumer goods company based in the USA. Filtrete specializes in air and water filtration and offers an air purifier range comprising of three different size air purifiers.
The Filtrete Ultra Make clean air cleaner is advertised as featuring "state of the art filtration technology"[1] and "the perfect balance of low noise, high clean air commitment rate and value for money"[2]. The unit of measurement is recommended as being suitable for rooms upward to 34m2 (365ft2) and is said to offer a "99.9% filtration rate of big particles". The manufacturer also says that the Filtrete Ultra Clean air cleaner has a "28% higher airflow than a HEPA purifier"[3] and that the air cleaner is "99.9% effective at removing particles from the air which passes through the purifier"[4].
The Filtrete Ultra Make clean is clearly marketed towards people with general allergies and animate difficulties[five]. Filtrete, nor any of its retailers, still, requite whatever concrete details nearly the actual filtration efficiency of the air purifier every bit a whole, its filter or of its airflow.
Review:
When nosotros opened the Filtrete Ultra Clean air purifier nosotros were pleasantly 
surprised past the depression key only modern blueprint of the unit. The size of the unit does not make it besides overbearing on space and will 'fit in' with nigh modern offices or homes.
The marketing material on the box is relatively gimmick-gratis and does non make obvious exaggerations in terms of what is realistic to await from an air purifier in this price range. However, on the Filtrete website, the air purifier is advertised as existence "99.ix% effective at removing particles from the air which passes through the purifier"[6]. On another page on their site, Filtrete says that the unit "captures 99.ix% of particles from air passing through the filter"[7]. Information technology is of import hither to point out that in that location is a large deviation between these ii quotes. A unit'south 'whole system filtration efficiency' is non the same as a units 'theoretical' filter medium filtration efficiency. Filtrete makes information technology sound as if the Ultra Clean Large Room Air Purifier has a whole system efficiency of 99.ix%.
Now the obvious question is: 99.9% of what? Sticks and stones? Normally we 
would assume that the pct relates to particulate pollution at 0.3 microns (which would be the manufacture standard). Simply that is not the example hither as Filtrete states that 99.9% only relates to 'large particles', without explaining how they ascertain 'big particles'.
It is a scrap curious that Filtrete is not giving a more precise filtration efficiency. It is, after all, the fine and ultra-fine particulates that people intendance most most, as they are the most harmful to your health and the most difficult to filter out of the air. An air purifier with a low filtration efficiency for fine and ultra-fine pollution will be of little use for most people with mild to astringent allergies and would certainly only provide a very limited to no protection from common contagion such as traffic pollution.
The type of filter used in the Filtrete Ultra Make clean Air Purifier is an electrostatic
polyester mesh filter. The filter will have a small static charge when it is new (that's why information technology is wrapped in plastic and should be used as soon as it has been unpacked) that helps to collect and retain pollution. This kind of filtration is, however, not great in achieving a) a consistent filtration efficiency, b) an especially high filtration efficiency over a given period of time, and c) a long filter life.
The Filtrete Ultra Clean does not have a pre-filter of any sort and as a result, larger particulates clog upwardly the electrostatic filter more speedily – resulting in a relatively short filter life of only 3 months.
The Filtrete Ultra Clean also does not have whatever gas or chemic filtration. This means it volition take footling or no effect on common airborne gasses, chemicals, and odours such as VOCs, traffic fumes, cigarette smoke or pet dander. This is a drawback and makes the unit unsuitable for people who suffer with rhinitis, asthma or Multiple Chemical Sensitivity.
Airflow & Filtration Efficiency:
The Filtrete Ultra Clean is marketed as beingness designed for room sizes up to 34m2 (365ft2). The manufacturer and its retailers, however, do not list the actual airflow of the air purifier anywhere. Instead, Filtrete only lists the Clean Air Commitment Rate (CADR) of the unit. There are several reasons why we practice not like to use CADR ratings. 1 is that CADR testing is not especially objective (equally information technology is the association of manufacturers that does the testing). Furthermore, the exam is flawed as it only tests units for 120 seconds and does not accept gas and chemical contagion into account (to find out more well-nigh CADR visit our CADR weblog postal service).
Then information technology is disappointing that at that place is no data on the actual airflow and filtration efficiency of the Filtrete Ultra Make clean air cleaner. We contacted Filtrete and likewise a couple of its retailers just did not receive any adequate responses. This made usa a bit sceptical of the units actual performance, as it seems odd for a manufacturer non to release the ii most of import performance indicators of air purifier and only – misleadingly so - say that information technology has a "99.9% filtration rate for large particles".
In the Us, Filtrete offers a similar electrostatic polyester mesh filter with five 
different filtration efficiencies. These filters range between a MERV (Minimum Efficiency Reporting Value) 8 and 15. The highest MERV rated filter (and most expensive one) that Filtrete offers are the Aristocracy 2200 which has a filtration efficiency at 0.3 microns of 95%. But again, as it is an electrostatic filter, the question is how the filtration efficiency will alter over time.
Information technology is obvious that the Filtrete Ultra Make clean air purifier is not designed to exist leakage free. This means that unfiltered polluted air tin can bypass the filter and be released back into the room. As the Filtrete Ultra Clean'south electrostatic filter becomes more loaded, more and more pollution escapes by the filter. This obviously hampers the air purifier's efficiency to properly clean the air.
The Filtrete Ultra Clean air cleaner comes with what is advertised as a "filter life indicator" (See Image ane). This indicator is more of a 24-hour interval countdown timer. It counts down 90 days earlier reminding the owner to replace the filter. It takes no account of the number of hours used or speeds setting the unit is running on, and as a consequence is of little apply. Yous might as well set an alert on your mobile phone or reckoner to remind you to replace the filter.
There is too somewhat of a design error with the Filtrete Ultra Clean Air Purifier in and so far that the unit of measurement has an open, uncovered tiptop (where the clean air comes out). This open up surface is prone to collect dust when the unit of measurement is switched off (Encounter Epitome 6). This is inconvenient, every bit it is difficult/impossible to simply clean the inside of the Filtrete Ultra Clean and if the air purifier is switched on again, the collected dust is blown back into the room. Thus, we would recommend to encompass this part of the unit when the air purifier is in storage or not used.
Summary:
The Filtrete Ultra Make clean Big Room Air Purifier is a good but also very basic air purifier. Information technology is not suited for serious air pollution concerns or people suffering with asthma, MCS or other severe allergies.
The filter will have to be changed oftentimes, and the filtration efficiency tin can significantly change the longer the filters have been used. The lack of activated carbon means that the Filtrete Ultra Clean is not able to bargain with odours, VOCs and other harmful gasses such as traffic fumes.
The air purifier is non leakage complimentary, which is excusable for an air cleaner in this toll range (and if you are not dealing with a serious contamination effect or astringent allergies and asthma). However, what is not excusable is that the manufacturer is overly secretive virtually the air purifier's actual performance in terms of filtration efficiency and airflow - to the point that we feel the information Filtrete is providing is misleading. If y'all buy an air purifier you need to know the units actual filtration efficiency and airflow, and it is the manufacturer's and the retailers' responsibility to provide this information to you.
