A modern and quality product from Airmega, 300S its basically 300 with added Wi-Fi integration with airmega app and Amazon Alexa. Sharing the same dimension as 300 with 13.6 x 21.2 x 13.6 in/ 21.4 lb weight, Airmega 300S build quality is second to none with no visible gap at all. Front design is as clean as it gets with only prominent ring indicator that shows surround room air quality. Instead just back air inlet in some model, Airmega 300S utilize dual air inlet that works wonder with 2 Pre-filter on each side. Controls is located at top with added Wi-Fi indicator along with fanspeed, Smart mode and dual filter change indicator (Pre-filter/ Max2). Other common features available in both 300/ 300S including 4 stage filtration, Smart mode (Auto/ Sleep/ Eco), 4 fan speed, separate pre-filter/ HEPA filter indicator based on runtime, 30 days satisfaction money back guaranteed and 5 years manufacture warranty.

Here is where the differences plays it part. Airmega 300S comes with Wi-Fi support which allows you to manage your air purifier via Airmega mobile IoCare App. Available in both iTunes and Google Play, pairing Airmega 300S is pretty straightforward for both iPhone and Android phones (higher end model) once you are used to standard procedure. Through Airmega’s IoCare app, you can remotely control your air purifier fanspeed, switch to Smart/ Sleep mode, real-time air monitoring plus Indoor/ Outdoor Air Quality Report and scheduler/ timer. While timer comes with pre-set 1, 2, 4, 8 hours setting, scheduler is no doubt our favorite where you could program up to weekly schedule to turn on or off the air purifier. Airmega 300S also works with Amazon Alexa where you could link it via devices like Amazon Echo. Standard list of voice command include activating/ deactivating the air purifier, switching to Smart/ Sleep mode, altering the fan speed, set timer, check filter life status and air quality.

Comes in standard 4 fanspeed, Airmega 300S has a toned down airflow performance and purifying coverage, at 1256 sq. ft. with 2 air charges every 30 minutes and 628 sq. ft. with 4 air charges every 15 minutes. There is plenty of punch even if you opt for the higher 4 air charges purifying. Great for residential user at living hall, basement or even bedroom.

The familiar 4-stage filtration setup, Airmega 300S works exactly like Airmega 300 with dual Pre-filter on both side with Green True HEPA filter and Activated Carbon filter in its core. Every time when Airmega 300S pulls air into the machine, the first-stage pre-filter on each side would block out large contaminants like hair leaving only small particles alone in the journey. With only micron size allergens left, the Green True HEPA filter would unconditionally traps all germs, bacteria and viruses at an effective rate of 99.97%. For smoke, odor and gases, the Activated Carbon filter would come into play with an efficiency rate of 99% before releasing purified air back out. Sadly there is no ionizer or similar technology available in any of the Airmega models.

Airmega 300S 22 - 52 dB noise level might not be the most silent air purifier around, it is still considerably silent especially at sleep/ low speed and only audible background noise at higher speed. Power consumption wise 6 - 57 W its not too shabby given the number of airflow output, expect slightly lower consumption rate if the air purifier is constantly operated in Auto/ Sleep mode where the fanspeed will only go higher is the air quality is not at ideal level. Also there is Eco mode where Airmega 300S will automatically stop the fan from spinning if the surrounding air quality is good for at least 10 minutes.

^ Airmega 300S replacement filters estimated cost
Airmega air purifier is not your typical budget-friendly model, furthermore Airmega 300S is the premium version to 300S so naturally the price tag would be even higher. Is the Wi-Fi feature worth the extra dollar for an identical specification to Airmega 300? You only can decide. What we do like its the remote access and scheduler that is only available via the app along with its high-performance output. On another spectrum, the mandatory filter replacement cost is not the most expensive in its class as you only need to replace one Max2 filter on a yearly basis. FYI Max2 filter is bundled with Green True HEPA filter and Activated Carbon filter.

The challengers

Airmega 300

Airmega 300

Drop the Wi-Fi connectivity and price will drop even further down.
Airmega 400S

Airmega 400S

Highest range in Airmega series that also comes with Wi-Fi support. Highest price is undoubtedly the biggest obstacle.
