About Alen T100 and T300 air purifiers

Both Alen T300 and T100 air purifiers are similar to the tower air purifier Alen T500. These two are compact and is more space-saving. These two air purifies are apt for condos and small rooms. The coverage range for these is 125 and 156 sq ft on an average for 6 air changes in an hour. This coverage ensures the removal and most of the allergens from the air and makes the room asthma and allergy-friendly. 

Alen T100 can work on using only one HEPA-Fresh filter while the T300 series need two filters at a time. The same filters need regular replacement every 6 months. The filter change indicator has got 6 bars which have 2 bars each for green and yellow and one for red. The bars start with 2 green initially and after 2 months one yellow will illuminate. One bar is illuminated with each passing month and by the time all 6 bars including the red illuminates, it is time to replace the filter.

In addition to the HEPA filters, pre-filter and the carbon filter layer,  there is also a UV lamp that kills the bacteria and the microbes. The pre-filter traps the larger air particles so that they do not go and clog the HEPA filter. The activated carbon layer at the back of the filter removes the milder odours from cooking and other sources. The odour removal is not as effective as one may expect but it is positive when used in a small and confined area. 

These Alen air purifiers have ionizer in the device that makes the air particles charged so that they are naturally attracted to the electrostatically charged HEPA layer. Simply pressing the ION button will make it ON or OFF. 

As for the electric and other safety matters concerned, both Alen T100 and T300 needs an input current if 120V and is better used within the US. Safety measures advice that the devices are to be connected directly to the power socket and not to any extension cords or adapters. They are also to be kept at least 6 inches away from heat sources and 2 ft away from walls, curtains or furniture. Choose the fan speeds from the 3 and 4 choices for Alen T100 and T300series respectively. 

Alen T100 HEPA-Fresh replacement filter: TF30 work mechanism

  • The Alen T100 HEPA-Fresh replacement filter: TF30 has 2 filters in the pack and each filter will have three layers of air filtration. The pre-filter will stop the large pollutants and help extend the life of the HEPA filter. 
  • The HEPA layer is charged and the ionized air particles are attracted to this layer easily so that they do not escape to settle down in the room. The air circulation ensures that the charged particles reach the HEPA filter. Here, the dust, pollens, allergens, and other airborne pollutants are filtered. 
  • The carbon filter comes the last where the old odors are removed. Do not expect the major change in the odors around but there is a significant difference nonetheless. 

The ioniser in the air purifiers work safely without clung any ozone formation. The device will only charge the air particles with an additional electron so that they can reach the positively charged filter sooner. The ioniser button can be switched off if you do not wish to operate it But it is recommended for the safer and effect time air filtration, Since the HEPA filter is charged already, the ionising the air particles will enhance the performance of the filter as well as the air purifier.
