Let’s begin with the design and dimension. Coway Airmega 150 is a three times winner of the international design awards which says a lot for a device that is targeted at a budget crowd. The simple and clean aesthetic blends seamlessly without hindering the functionality. Air pollutants are drawn in from the back and distributed at the front air outlet. Moving and finding a place for Coway Airmega 150 is easy thanks to the thin 13.3 inches width, 18 inches height, and 6.5 inches in depth. The 15.4 pounds weight is not the lightest, but you can still carry it for room to room purifying when there is a need to do so. Build quality is great with tight-fitting that prevents any off-gassing. The EZ release design filter is intuitive to slide out the pre-filter for quick washing and drying. As always, Coway Airmega 150 is UL listed, CARB approved and comes with 3 years limited warranty that covers the motor and electronic parts.

Moving to the control and usability. Every functionality of the Airmega 150 air purifier can be managed via the top control panel. You can adjust the 3 fan speeds (low, medium, high) or activate the auto mode that will only use higher fan speed when a high concentration level of pollutants is detected in the room. Otherwise, the air purifier will remain at a low speed. To the left, there is a real-time air quality monitor that works with the pollution sensor to display room quality. In colored LED, The AQI will illuminate in blue when air quality is good, green when air quality is moderate, yellow when air quality is unhealthy, and red when it is very unhealthy. There is also a deodorization filter plus HEPA filter indicator that will alert you to replace the filter every 6 months and the latter 1 year. All that is missing is the much loved timer button and sleep mode.

Enjoy a fresh burst of energy without the exuberant cost. Running at full capacity, Airmega 150 air purifier can cover up to 214 square footage of air space. Great for medium room sizes such as bedroom, small living room, kitchen, basement, and single garage. The compact size also makes it an ideal dorm, office cubicle, or nursery home with limited spaces and poor ventilation. We highly recommend you leave it at Auto mode and the air purifier will intelligently decide what speed is best to tackle the surrounding air quality.

Filters And Performance

Coway Airmega 150 uses the try and tested 3-stage HEPA filtration. The outer pre-filter captures PM10 particles including common dust, hair, and lint. The pre-filter is washable and can be reused as it tends to get clogged quickly. With no large particles passing through, the Green True HEPA filter traps 99.999% microscopic particles as small as 0.01 microns in the air including mold, pollen, mildew, pet dander, germs, bacteria, and viruses. The deodorization filter neutralizes 99.99% of odors, cigarette smoke, food smells, musty mold, volatile organic compounds, and other harmful gases e.g. pesticides, car fuel, wood fire. Clean air will then be circulated out at the front leaving only breathable fresh air to enjoy. Perfect for asthmatic, hypersensitive, or sick persons with a compromised immune system.

Whisper-quiet operation is always a forte with Coway Airmega and the same applies here. You can use it during work, sleep, or even during yoga that needs absolute tranquility. Power consumption is equally good that uses less than 60 watts when running at max speed. Eco mode will activate automatically that stops the motor fan from spinning after 10 minutes of good air quality. Coway Airmega 150 air purifier is designed to run 24/ 7 at maximum air cleaning efficiency even after years of ownership.

An excellent starter air purifier for those that need clean air with a tight budget. Coway Airmega 150 is our favorite cheap air purifier replacing the previous favorite Winix 500-2. It is well-made, well-featured, and performs reasonably well. The low 40 dollars annual filter cost is the biggest attraction to me. You never have to worry about the costly filter replacement with Coway Airmega 150 air cleaner. No more succumbing to third-party filters just to save a quick buck. A rare sight in modern devices.
Retailing at 189.99 before discount, you can easily get Coway Airmega 150 for under 150 dollars at Amazon depending on which color you opt for. The white version is often sold the cheapest but do look out for seasonal sales that would really drive the price down. You can try your luck on the Coway Airmega website but the offering is not as attractive as Amazon. Other online retailers like Walmart, Costco may also carry the brand with the usual perks e.g. free shipping, bundled deals, and a 30-days return policy.

Pros

  • Under 150 dollars (after discount) for a complete 3-stage HEPA air purifier.
  • True HEPA filter that captures 99.999% biological pollutants including viruses as small as 0.01 microns.
  • Compact body with a thin profile that can fit in any home.
  • Built-in sensor to support autonomous mode and real-time air quality monitor.
  • Dedicated deodorization carbon filter removes toxic smoke and odors that are harmful to our body.
  • Easy to maintain and replace with filter replacement set around 40 dollars annually.
  • 3 years official warranty that covers motors and electronic parts.

Cons

  • Limited air coverage. Only suitable for medium room size.
  • No timer, no ionizer, no auto-sleep mode as standard.
