Airmega 400S App-Enabled Smart Air Purifier (Covers 1,560 sq. ft.), True HEPA Air Purifier with Smart Technology, Compatible with Amazon Alexa and Google Home, White (111012)

We purchased this unit in June 2022, nearly 3.5 years ago. That said, this review is coming from a place of experience with this air purifier. We had just adopted two cats that were born in the bushes outside our home, and I don't particularly care for cats (or more specifically, the smell of cats)! I was concerned about the price of this machine, not because it was crazy expensive compared to other machines that claim to be able to do what this purifier does, but because I didn't want to spend even half of what this thing cost just to keep the house from smelling like cats. On top of that, I didn't want to have to keep buying filters for it. I chose to bite the bullet and purchase this because I figured that if this device could keep the cat smell to a minimum, it would be worth every penny. The recommendation is every year or two, but they are so easy to clean that we were able to extend the filter life quite a bit! The outermost screen filters are quick and easy to get the dust off. It takes about one minute per filter (one on each side) to vacuum off. We clean these filters every 45-60 days. The innermost filters - the big ones with the charcoal - we clean every 12 months. Those take a little longer to clean, but no more than 5 minutes with a vacuum attachment. Everything on this device is easy to remove and replace. Now for the important part... Until just this very week, I have never - and I do mean NEVER - noticed a cat smell in our home. My in-laws have a cat, and they have commented several times over the years how amazing it is that our home never smells like cats - or any odors for that matter! My sister-in-law is allergic to cats but doesn't have any issues at our house. Fast forward to today, I have grown a bit fonder of the cats but still don't like cat smells! I came to Amazon today to purchase my very first set of replacement filters, if that tells you anything about the longevity of these filters! I decided to leave this review just in case anyone else is on the fence about this air purifier. It works. Perfectly. All day. Every day. Additionally, I no longer use expensive HEPA filters in our HVAC system because this purifier takes nearly everything out of the air that those would catch anyway. For anyone who's curious: We have a 1900SF home. I was able to find a great location for this fairly close to the middle of our home so that it purifies the entire house. I go weeks at a time without even realizing this thing is in the room - it just blends in and disappears! If it detects odors, it will speed up for a brief period of time, but almost always runs at the lowest speed - nearly silent. I'm certain that this would even work in larger homes than ours, because in our home it typically only runs at 25%. There are a number of controls so you can adjust the speed, setting, schedule, etc., but we never use them. We just set it and forget it. The power this unit can produce (and the amount of air it can move) is incredible. This purifier brings air in from the sides of the unit and exhausts it out from the top, creating perfect circulation. As an added (undocumented, unsupported) function, anything you place near the top of this unit (potpourri, air diffusers, essential oils, etc.) is quickly dispersed throughout the home.

We got 300S WHITE in April 2020. We were affected by the wildfires in the Bay Area and during the Covid pandemic, so we needed fresh air. Coverage. 300S / 300 model can fully change the air every 30 min in 1,256 sq. ft coverage and assuming the height of a ceiling to be 8ft. If the coverage is 628 sq. ft , the air will be changed every 15 min. 400S / 400 model can fully change the air every 30 min in 1,560 sq. ft coverage and assuming the height of a ceiling to be 8ft. If the coverage is 780 sq. ft , the air will be changed every 15 min. You can use this logic and calculate approximate numbers for your place. Noise level. The noise level, based on the attached Certificate of Performance, ranges from 22db - 52db subject to the mode of operation. We only find it slightly noisy when it runs an intensive cleaning, otherwise, it goes virtually unnoticed. No weird smell. It's noteworthy to mention that unlike another purifier we previously tried that had a strange filter smell, the 300S model runs odor-free. The air quality feedback. The interactive light feature on the model provides real-time air quality feedback. If left on, the light changes color according to the air quality as follows - — Blue and green for good air quality. — Green and yellow for moderate quality. — Yellow and pink for unhealthy air. — Pink and red for very unhealthy air conditions. Performance, maintenance, and management. - The model comes with five operational modes (Smart, night, level 1, level 2, and level 3). - It has an auto setting feature that turns on automatically when the air quality deteriorates, a common occurrence when we accidentally burn food while cooking. - It incorporates a two-filter system, offering convenient notifications reminding us when to clean the pre-filter (just a simple wash) or replace the inner filter (about $43 per filter). - The air cleaner can connect to Wi-Fi and comes with a mobile app, which pushes air quality notifications to your phone in real time. - The scheduling control feature allows us to set the operation based on our daily routine. Other: - It's light and portable, so moving it around the house is quite easy. - The design is aesthetically pleasing - the white variant looks trendy and minimalist, which adds to our interior decor. - The durability should be highlighted - it has been four years, and it’s still working flawlessly. Overall, we are thoroughly satisfied with the 300S WHITE air cleaner and highly recommend it if you are looking for cleaner indoor air.

Es una maravilla. Ayuda muchisimo con las alergias. Tenia meses con rinitis alergica y este purificador ha ayudado mucho a mitigar los sintomas. (Sí eres alergico a polvo y acaros también compra una aspiradora para cama/muebles)

No tengo un aparato para medir la calidad del aire, pero cuando cocinamos si elimina olores y no es muy ruidoso ni desprende algún olor a plástico. El filtro dice ser 100% HEPA.

Funciona perfecto! Se puede controlar con el app y tiene una funcionalidad Smart que automatiza todo el rollo. Excelente capacidad para cuartos grandes

No entiendo todos los comentarios que dicen que no sirve la aplicación. No he tenido ningún problema. Excelente producto. Muy silencioso. Me ha bajado mucho la alergia

Compre este purificador pensando en qué por sus características iba a poder a eliminar olores de tabaco, sin embargo, además de no hacer nada contra esos olores el purificador emite un olor a plástico quemado el cual resulta más desagradable que el olor a cigarro.
