The starters

Alen Paralda dimension
11 x 28 x 7 in
(27.9 x 71.1 x 17.8 cm)
Alen Paralda weight
15 lb (6.8 kg)

A beauty among tower air purifiers, Alen Paralda do look smaller than its 11 x 28 x 7 in suggested size thanks to the transparent panel and curvy sidelines. 15 lb weight is standard tally with its size while build quality is solid similar to most Alen air purifiers. Overall Alen Paralda would not take up much space but is a tad taller for desktop use. On to features, beside the standard 3-stage filtration including Ionizer, ENERGY STAR rated, timer, filter light indicator, Alen Paralda also comes with 4 fan speed, LCD display with soft-touch controls, night light, upgraded HEPA-silver filter (more on that later), Hassle-free filter replacement with self-closing cover, hidden cord wrap system that hide unused cord underneath the air purifier system and lifetime warranty.

Airflow, speed, and CADR

Alen Paralda coverage
Purifying coverage
500 sq. ft. (46 m2)
Alen Paralda fanspeed
As a tower-type air purifier, Alen Paralda has an impressively wide 500 sq. ft coverage flew from the back and out from the side. It can cover most living hall, bedroom, kitchen or even offices within its coverage. 38 - 117 cfm airflow delivery rate is not the quickest but it's sufficient enough to support the 4 fan speed.
Alen Paralda dust CADR
114 cfm (194 m3/h)
Alen Paralda pollen CADR
Pollen CADR
114 cfm (194 m3/h)
Alen Paralda smoke CADR
Smoke CADR
114 cfm (194 m3/h)
CADR is at an average of 114 cfm tested by ENERGY STAR. Again not the best but it will do its job. For a more comprehensive comparison, use the comparison table link above.

What’s inside count

^ Alen Paralda filters/ lifespan/ price
Alen Paralda default 3-stage filtration would trap most household non-odor type filtration. For start, the cover pre-filter would capture dust, hair and other large-sized airborne pollutants. For smaller size allergens that are not seen throughout naked eyes, you'll have the HEPA-Silver filter standing by. For even more effective filtration against bacteria, chemicals, smoke, and odors, choose one of the HEPA filter upgrades as seen above. Last but not least, Alen Ionizer is all fired up when dealing with unclear airborne pollutants within its purifying range.

Keep it down

Alen Paralda noise level
Noise level
37.5 - 60 dB
Alen Paralda power consumption
Power consumption
56 W
Alen Paralda 37.5 - 60 dB noise level is subtle at lower speed and acceptable noise at 3 - 4 speed. Our definition of acceptable noise means its loud but at least it's at normal conversation. Choose fan speed 1 to 2 for night time use. Power consumption is not too far off from most home appliances at an average of 56 W depending on fan speed.

At what cost

Alen Paralda MRSP/ RSP
+- 324
Alen Paralda annual filter replacement cost
Annual Filter Cost
+- 59 - 118
^ Replacement filters/ estimated cost
Alen Paralda is cheaper than all BreatheSmart series models although we would not categorize it under cheap. There is also Alen T500, a cheaper and better value tower air purifier. Annual filter replacement is not the cheapest as filter lifespan last between 6 - 12 months compared with BreatheSmart that could last up to 18 months. Prices would further push up if you opt for the upgraded filter.

Alen Paralda VS the challengers

Alen T500

Alen T500

Stronger airflow yet cheaper price and annual filter cost with same purifying coverage. Does not have the looks, 3 fan speed, and basic bundled filter.
Alen BreatheSmart FLEX

Alen BreatheSmart FLEX

Top up a bit more and you'll get the compact version BreatheSmart Flex which triumph on airflow performance and coverage.
