Filters and Annual filter replacement cost All Alen air purifiers comes with 3-stage filtration with optional HEPA filter upgrade. For dust, hair and other large pollutants, you have the permanent and washable Pre-filter standing by. HEPA filter would capture smaller micron size particles and by default most air purifier comes with HEPA-Pure filter (dust and allergens). Optional upgrade includes HEPA-Silver (Bacteria and Germs), HEPA-OdorCell (Smoke and Heavy Odors) and HEPA-FreshPlus (Chemicals and VOCs). Last stage Ionizer would ensure all airborne pollutants would be captured or dropped to the floor. On to annual filter replacement cost, expect $44 - 138 price range varies on filter type and lifespan. BreatheSmart series filter lifespan is at an average of 6 - 18 months while tower air purifier is at an average of 6 - 12 months.
WhisperMax technology Help keeps the motor fanspeed volume down with precise tuning and aerodynamics.
Smart Filter Light Calculate filter lifespan based on usage and surrounding environment air quality.

Overall airflow performance

Purifying coverage, Airflow, Fanspeed and CADR The current list of Alen air purifiers lineup has wide purifying coverage for large area between (500 up to 1100 sq. ft. and strong airflow delivery rate between 28 - 286 cfm. Based on the purifying radius all Alen air purifiers would cover space area from bedroom, living hall, basement, meeting room,garage and kitchen. Almost Alen air purifiers comes with 4 fanspeed for better airflow management while CADR tested by ENERGY STAR sit between 114 (Paralda) to 300 cfm (BreatheSmart).
Noise level and Power consumption In general Alen air purifier (42 - 56 dB) noise level is not the most subtle at low speed but moving up the noise level is perfectly bearable even for normal conversation. As for power consumption, its averaging between 30 - 105 W, again not the lowest but on normal operation between 2 - 3 speed, it's considerably cost-efficient given its optimal airflow delivery rate and applicable area. Most Alen air purifiers also comes with Auto mode which works well in managing the air purifier power usage.

Complete list of Alen air purifier reviewed

In no particular order, here is our most recent list of Alen reviews: Alen BreatheSmart 45i,  Alen BreatheSmart 75i,  Alen BreatheSmart Classic,  Alen BreatheSmart FLEX,  Alen BreatheSmart FIT50,  Alen T100,  Alen A375,  Alen T500,  Alen Paralda, 

Which Alen air purifier to go for?

Thanks to the changeable front panel cover. Alen BreatheSmart  is still a refreshing model even though its been in the market for number of years. On first look it's very hard to tell apart between the other BreatheSmart model, Alen BreatheSmart stands top-of-the-line externally and internally with large body  to accommodate its outstanding filtration. Underneath the "hood", Alen BreatheSmart superb 1100 sq. ft. purifying range and consistent airflow distribution is the best in BreatheSmart  series and one of the best in the large purifying group. Features wise is very generous besides the 3-stage filtration (Pre-filter, selected HEPA filter and Ionizer), 4 fanspeed with Auto mode, Smart Filter Light filter replacement indicator, child-lock, ENERGY STAR rated and Lifetime warranty.

What is the cons? Not much beside the expensive list price, typical loud noise at high speed and lacks dedicated carbon filter option. If you are going with this model, we recommend upgrading the filter to HEPA-OdorCell or HEPA-FreshPlus to cover smoke and odors based pollutants.
  • Plenty of swappable wood trim front cover design.
  • Wide purifying coverage, superior airflow delivery rate and highly adjustable (up to 4 speed).
  • Up to 3 optional filter upgrade to choose from depending on your needs.
  • Ionizer could be turn on or off.
  • Longer lasting filters (up to 18 months) depending on usage volume/ air quality.
  • Accurate Smart Filter Light replacement indicator that calculates based on usage/ fanspeed/ environment.
  • Abundance of features - SmartSensor (air quality sensor), auto mode, filter life timer, pre-set timer.
  • Child friendly machine with locking control panel and safe vent guard.
  • Alen unique Lifetime Limited Warranty.
  • Lacks odor filtration on bundled HEPA-Pure filter (Optional filter upgrade required).
  • No dedicated odor carbon filter which could come in handy as filter replacement can be done separately.
  • Noisy at highest speed nevertheless Auto mode does come to rescue.

Alen BreatheSmart FIT50 is slotted right in the middle between the standard BreatheSmart and FLEX. It still has a remarkable purifying coverage at 900 sq. ft. and airflow delivery that outshines other similar segment air purifier. BreatheSmart FIT50 airflow distribution might not be on the same par as  standard BreatheSmart, but what you do get in-return is a smaller and more cost effective air purifier with the same set of features and wide variety of changeable front panel. Other features include SmartSensor with Auto/ Sleep mode, child-lock, filter replacement indicator and many more. As with other BreatheSmart models, we recommend upgrade the filter to HEPA-OdorCell or HEPA-FreshPlus for carbon deodorization missed in the default filter.

With the same plus point as Alen BreathSmart, FIT50 weak points is no difference either so we will not go through it again. One thing worth noting is annual filter replacement cost is the highest between the 3 though not by a big margin. In short Alen BreathSmart FIT50 is "THE balanced one" that suit most people.
  • Multiple color option/ wood trim design front panel cover.
  • Excellent purifying coverage/ airflow delivery although its less effective against standard BreatheSmart.
  • Up to 3 specialist filter upgrades (HEPA-FreshPlus , HEPA-Silver, HEPA-OdorCell).
  • Ionizer is optional that can be disable via the button.
  • Longer lasting filters (up to 18 months) on regular use.
  • Smart Filter replacement indicator that calculates filter lifespan based on usage/ fanspeed/ environment.
  • 4 fanspeed with Auto mode, SmartSensor, pre-set timer.
  • Child friendly machine with safe vent guard and locking control panel.
  • Lifetime Limited Warranty.
  • HEPA-Pure filter lacks odor filtration and optional filter with deodorization requires top up.
  • No dedicated odor carbon filter to support the HEPA filter lifespan.
  • Noise is clearly audible at higher speed although still bearable.

"THE compact one" for BreatheSmart model, Alen BreatheSmart Flex might comes with the smallest dimension, lightest weight and weakest airflow performance, at 700 sq. ft applicable area. its no slouch either. Powered by the same 3-stage filtration with Pre-filter, Ionizer and 1 of the 4 types of HEPA filters, BreatheSmart Flex has the advantages over the other model in price point and size. Standard equipment includes a 4 fanspeed, our favorite swappable front panel (optional purchase), Smart light filter replacement indicator, Ionizer with on/ off button, timer and lifetime warranty cover by the manufacturer.

As the smallest in its series, weaker airflow delivery rate and coverage is expected, what's left out in the equipment list is Alen's  SmartSensor which is a requirement to support Auto mode. In short any of the 3 BreatheSmart air purifiers would do a bang up job but we would go with either FIT50 or standard BreatheSmart simply for the Auto mode.
  • Changable front panel with tons of modern wood trim design.
  • Consistent and strong airflow delivery rate that supports the wide purifying area.
  • Up to 3 optional filter upgrade that is excellent against allergens and odors.
  • Longer lasting filters compare with similar segment models although that would also depend on usage frequency.
  • Built-in timer (2, 4, 12 hours).
  • Child friendly machine with locking control panel and safe vent guard.
  • Lifetime Limited Warranty.
  • Lacks odor filtration on bundled HEPA-Pure filter (Need to move up with one of the optional filter).
  • No dedicated odor carbon filter that separates from the HEPA filter that would reduce each filter workload.
  • Noisy at highest fanspeed although not the worst in its class.
  • Lacks advanced filter replacement indicator (only basic version), SmartSensor (thus Auto mode), Ionizer. All these is available in BreathSmart/ FIT50.

Outshine by its own BreatheSmart series air purifier, Alen Paralda might have a conventional tower framework, the wide purifying coverage and strong airflow return would suggest otherwise. It might have standard 3-stage filtration similar with how other Alen's air purifier is setup, the latest Alen Paralda actually comes an upgraded HEPA Silver filter that is great in removing bacteria and germs. Another highlight of Alen Paralda is it manage to cramp in filter light indicator,  programmable timer, digital display and still gets high airflow output. Combining the assurance of Alen Lifetime Limited Warranty,  Alen Paralda is the tower air purifier you should look out for.

As most tower air purifiers, the downside in space-saving size would usually eat up same performance efficiency when compare with conventional size air purifiers. Alen Paralda also lacks Smart Filter Light and have higher annual filter cost then the next item in the list which you should seriously consider as well.
  • Extensive purifying applicable area as with T500.
  • Comes with upgrade HEPA-silver filter.
  • Cable Management System that can hide excessive cords underneath the air purifier.
  • Top pulling filter change that can be done within minutes.
  • The option to turn off Ionizer when not needed.
  • On/ Off Night light keep your setting when the air purifier restarted.
  • Programmable timer.
  • At highest speed 4 setting, only standard fan white noise could be heard.
  • Amazing lifetime limited warranty.
  • Slightly weaker airflow delivery rate.
  • No dedicated deodorization filter.
  • Optional purchase is needed for odor filtration or dealing with strong chemical.
  • Lacks quality sensors for monitoring and enabled Auto mode.

Lets be clear,  Alen T500 is no looker nor it's a benchmark air purifiers; it shouldn't be. What Alen T500 should be is a reasonably price, compact, lightweight tower air purifier with wide purifying coverage and dynamic airflow. Utilizing the same 3-stage filtration method that includes pre-filter, HEPA filter (up to 4 selectable option) and Ionizer, annual filter replacement cost is on the cheap side thanks to the achievable 12 months filter lifespan. Alen T500 is also well equipped filter replacement indicator, digital display with 24 hour timer and Lifetime warranty. Another plus point worth mentioning is that the CADR and airflow delivery rate is actually better than Alen Paralda.

Again tower air purifier might not have the best performance VS price point ratio compare with conventional air purifier, Alen T500 HEPA-Pure filter also does not comes with any deodorization and there is no standalone carbon filter to addon to its filtration. Between Alen Paralda and T500, We would highly recommend Alen T500 if you are looking for a space-saving yet capable tower air purifier.
  • Comprehensive purifying coverage for a tower air purifier.
  • Easy to bring around thanks to the compact size and back handle.
  • Upgradable HEPA filters depending on your individual needs.
  • Covered by Alen lifetime warranty.
  • Ionizer function can be turned off.
  • Up to maximum of 12 hour timer.
  • Relatively subtle noise with loud but bearable noise at highest setting.
  • No stand-alone deodorization filter.
  • An optional filters purchase (HEPA-OdorCell) is required to deal with strong odor.
  • Lacks air quality sensors and Auto mode especially at this price point.
