Alen T100 Review

Alen T100 Review Summary

The Good: This stylish air purifier is affordable and comes with 3 in 1 filter that is easy to change.

The Bad: For some people, the size can be pretty awkward. It’s too tall to put on a table and too short (and hence, inefficient) to put on the floor.

The Bottomline: Regardless of the odd size, this is a good desktop air purifier. It also has a lifetime warranty and a safety feature not known in air purifiers at this price range. Shortlist this machine if you’re shopping for a desktop air cleaner.

What we like about the Alen T100 Air Purifier

Simple Filter: It rolls the pre-filter, HEPA filter (to trap 99.97% of airborne particles) and an activated carbon filter into one. This makes it easy for you to keep track when you need to change the filter.

Sleek design: The black stylish machine comes with touch buttons to control it’s 3 fan speeds. It also has a digital display – a feature most air purifiers this price don’t have.

Quite Silent: On low setting, you hardly hear the motor working and on high setting, it hums as loud as a desk fan.

Warranty: Like any other Alen air cleaners, the company backs it with a lifetime warranty, provided you change the filter every 6 to 9 months.

Safety: If the lid is opened, the machine will shut down automatically. Most machines at this price range do not have this feature.

But, we are concerned that :

• The filter costs the same ($49 annually) as the bigger T300, which covers more area and has more features.
• The T100 has no air intake grills on it’s side ( but the base of the unit does have a swivel to rotate the machine 25 degrees sideways)
• The unit also comes with a button to turn it’s ionizer on or off. Ionizers are known to emit ozone, which is harmful in large quantity. Alen Corp claims that the ozone this machine emits is far below the limit set by the FDA. If you’re worried, turn off this button.

Alen T300 Review

Alen T300 Air Purifier Review Summary

The Good: Stylish and full of features. Has a lifetime warranty and the filter cost is reasonable.

The Bad: No air intake on sides.

The BottomLine: With features you’ll only find in premium air purifiers, the stylish T300 tower air purifier is definitely a good buy. If you want an affordable air purifier for your kid’s room, this is a perfect choice.

What we like about the T300

Slim but packed with features: It has almost all the accessories of  it’s big brother – the high performance A375. The difference is it’s slimmer and is made to clean a smaller area.

Has UV Lamp: It also comes with UV lamp to kill bacteria in your air. Handy if you suspect you have floating molds due to damp carpets, etc.

Cheaper: And unlike many air cleaners, at around $45 to $60, the cost to maintain it is reasonable because apart from 1 UV lamp, there is only 1 filter (pre-filter, HEPA and carbon are combined) to change.

Easy: The T300 comes with digital display and a smart automatic filter change indicator that will let you know when to change your filter. There’s no need to mark your calendar.

Less Worry: Like any other Alen air cleaners :-

• This machine shuts down automatically if the lid is opened. A very important feature if you want to put it in your kid’s bedroom.
• Alen backs it with a lifetime warranty, provided you change the filter every 6 to 9 months. No other air purifier makers back their machines this long.

But we are concerned that:

• This tower air purifier has no air intake on both it’s sides. Thus, it may be less efficient compared to machines with 360 degrees air intake.
• The unit also comes with an ionizer button. Ionizers may emit ozone, which is harmful in large quantity. Alen Corp claims that the ozone this machine emits is far below the limit set by the FDA. If you’re worried, just leave the button switched off.

Alen A350 Review

Alen A350 Air Purifier Review Summary

The Good: The 3 in 1 filter is effective and easy to change.

The Bad: The top 2 settings are loud.

The Bottomline: If  your home does not have any serious smokes, mold or fungus problems, seriously consider the A350. It is effective, affordable and with the auto-shutdown feature you don’t have to worry if you dog or kids knocked it down while running around.

What we like about the A350

Easy to change filter: Unlike many air cleaners, there is only 1 filter to change (pre-filter, HEPA and carbon are combined) and you don’t need any special tools to do it.

Filter Indicator: To make sure you don’t forget, there’s a filter change indicator on it’s digital display.

Fan settings: There are 4 fan speeds. We suggest you use the lowest fan setting during your sleeping time.

Remote Control: Unlike it’s more expensive siblings, you’ll find a remote control to help you set the machine from the comfort of your bed.

Save Space: If your don’t like leaving it on the floor, you can mount it on your wall.

Optional Skins: And if you hate the plain look, there are 6 bright, funky skins for the machine ( older folks may hate the bright colors though!).

Less Worry: One of the biggest advantage of this air purifier is a peace of mind.

• Firstly, the machine shuts down automatically if the lid is opened. Very important if your have small kids or dogs.
• Secondly, the company backs it with a lifetime warranty if you change the filter according to the recommended time.

But we are concerned about :

• Noise: You may want to keep it at any of the 2 lowest settings if you’re going to sleep. Sleeping with the machine at the highest speed may feel like sleeping in a wind tunnel.
• Filter costs: The filter cost is at par with many other air purifiers that covers an area this big. You’re looking at $90 – $120 a year.
• Ionizer: The unit comes with an optional ionizer function. Ionizers may emit ozone, which is harmful in large quantity. The company claims that the ozone this machine emits is 92% below the limit set by the FDA. But if you’re still worried, just turn the ionizer off.

Alen A375 Review

Alen A375 UV Air Purifier Review Summary

The Good: An easy to change 3 in 1 filter with 2 UV lamps is versatile enough to clean and sterile the air of most homes.  Has a simple safety feature and lifetime warranty.

The Bad: The top 2 fan speeds are loud.

The Bottomline: If Alen A375 is a car, it would be a Honda Civic. It’s a simple, reliable machine with  better features and performance than most units at the same price. If you need an affordable machine that not only cleans the air but also sterilize it from floating germs or fungus, this is one of your options. Coupled with a lifetime warranty, this is surely one of the most attractive air cleaner in the market.

What we like about the Alen A375

The filter: Like other Alencorp machines, this one has a 3 in 1 filter – a pre-filter, a HEPA and an activated carbon all rolled into one. This helps make it easy to change your filter as well as ordering them (you don’t need to order separate filters at separate time like many air cleaners).

It also contains Photo-Catalytic Oxidation technology to help reduce harmful VOCs (VOCs are the harmful vapors that things like glue, formaldehyde and some aerosols emit.)

UV Lamps: It also comes with 2 UV lamps to kill bacteria in your air. Handy if you suspect you have molds under your damp carpets.

Easy: The A375 is also easy to use  because it comes with a remote control, smart automatic filter change indicator and a timer function. You can basically control it from the comfort of your sofa or bed.

Save Space: If your space is tight, you can mount it on the wall. And if you hate the plain look, there are 6 bright, funky skins for the machine ( older folks may hate the bright colors though!)

Less Worry: One of the biggest advantage of this air purifier is a peace of mind :-

• Firstly, the machine shuts down automatically if the lid is opened. Very important if your have small kids or dogs.
• And secondly, it has a lifetime warranty (if you change your filter at recommended interval).

But we are concerned about the :

• Noise: You may want to keep it at any of the 2 lowest settings if you’re going to sleep. Sleeping with the machine at the highest speed may feel like sleeping in a wind tunnel.
• Filter costs: The filter cost is at par with many other air purifiers that covers an area this big. You’re looking at $90 – $120 a year.
• Ionizer: The unit comes with an optional ionizer function. Ionizers may emit ozone, which is harmful in large quantity. The company claims that the ozone this machine emits is 92% below the limit set by the FDA. But if you’re still worried, just turn the ionizer off.
