Air Purifier Macro Max AS
How we chose
We started with coverage, since that decides whether a purifier suits a bedroom or an office. The 338S lists 856 sq ft, the 539AS lists 1079, and the 530S lists 967. The Macro Max AS carries an air quality indicator and a 3-layer filter with a 6-8 Months filter life, as does the 539AS.
Filtration and modes came next. The 338S uses a 3-in-1 HEPA Filter with 6 Levels of fan speed and a maximum air volume of 115 CFM. The 530S specifies 99.97 % filtration efficiency and particle retention down to 0.3 μm, with a CADR of 130 CFM. The 539AS offers Sleep, 1/2/3/4 gears and Automatic modes.
Then we set those specs against price. The 338S is $99.99, the lowest here. The 539AS is $119.99, which is $20.00 more than the 338S. The 530S is $129.99, $30.00 more than the 338S and $10.00 more than the 539AS. The Macro Max AS is $189.99, $90.00 more than the 338S, $60.00 more than the 530S and $70.00 more than the 539AS. Each of the four has held flat over the past 90 days, at its 90-day low.
Who should skip these
If your room is larger than 1079 sq ft, none of these three covers it. The 338S is rated for 856 sq ft, the 530S for 967 sq ft, and the 539AS for 1079 sq ft. For a bigger space, look at the Macro Max AS or another family.
Skip these if you want the purifier to tell you about air quality on its own. The Macro Max AS is the one here with an air-quality indicator. The 338S, 530S, and 539AS do not list one.
The Macro Max AS is $189.99, which is $90.00 more than the 338S, $60.00 more than the 530S, and $70.00 more than the 539AS. If an indicator is what you need, that is the gap to weigh.
How to choose the right one
Start with the room. The Air Purifier 338S covers 856 sq ft, which suits a bedroom or office, and it runs a 3-in-1 HEPA filter across 6 fan levels with a maximum air volume of 115 CFM. At $99.99 it is the lowest price here.
If your room is larger, the Air Purifier 539AS covers 1079 sq ft and adds Sleep mode, four manual gears and Automatic mode, for $20.00 more than the 338S. If finer filtration specs matter more to you than modes, the Air Purifier 530S is rated at 99.97% filtration efficiency down to 0.3 μm, covers 967 sq ft with a CADR of 130 CFM, and costs $30.00 more than the 338S — $10.00 more than the 539AS.
All three are at their 90-day low. The Air Purifier Macro Max AS, at $189.99, adds an air quality indicator and a 3-layer filter rated for 6-8 months; it costs $90.00 more than the 338S, $60.00 more than the 530S and $70.00 more than the 539AS.
