Cleaning Capabilities & Modes

The Idylis AC-2118 is capable of cleaning large rooms that reach up to 465 square feet. If you use it in larger rooms than this, its cleaning ability starts to diminish. Alternatively, if you use this air purifier in smaller rooms, you increase its effectiveness. It has relatively high CADR scores, which means it easily pulls smoke, dust and pollen particulates from the air.

This air purifier makes just over four air changes per hour, meaning all the air in the room passes through its filtration system once every 15 minutes. This makes the Idylis AC-2118 ideal for those who suffer from allergies or other breathing-related issues, as it pulls allergens out of the air quickly. The machine has two cleaning cycles: a carbon pre-filter and a HEPA filter. The carbon pre-filter captures larger debris, such as dust and hair. This filter also prolongs the life of your HEPA filter, preventing these larger elements from clogging it. The HEPA filter is designed to capture the smallest particles, ranging from relatively large pollen particulates to extremely small smoke particles. The machine does not include the extra cleaning stage of an ionizer. However, many prefer purifiers without this feature, as it emits trace amounts of ozone.

The Idylis AC-2118 includes an auto mode, a convenient feature that senses the ambient air quality in your home and adjusts its settings to maximize its cleaning effectiveness. The machine also includes a sleep mode that dims the panel lights and sets the fan speed on its low setting so as not to disturb you at night. This mode cleans the air without making a lot of noise and also conserves energy as a nice side effect of running on minimal settings.


Perhaps reflecting its ability to clean large rooms, this Idylis air cleaner is among the largest machines we reviewed. It weighs nearly 19 pounds, so it isn't the heaviest purifier we found but is still quite hefty compared to some. Storing it can be a little tricky, as it is the tallest and deepest machine we reviewed at nearly 30 inches tall and 13 inches deep. You'll want to dedicate some closet or storage space for this machine when you don't want to run it. Unfortunately, this air cleaner lacks handles to help you move it around the house as you need.

On its highest setting, the purifier produces an average noise level of 60 dB. To give you an idea of what this means, a whisper registers around 30 dB, while a phone ring usually reaches up to 80 dB. So you can run the Idylis in your living room or bedroom on its highest settings during the day without disturbing you too much.

This air purifier has one of the most sophisticated operational timers we have seen. You can schedule the machine to run between one and eight hours, and you can set the days of the week you want it to automatically turn on or off. This feature alone makes the Idylis AC-2118 a set-and-forget appliance, meaning you don't have to fiddle with the settings every day if you don't want to. The machine also includes a filter monitor that lets you know when you need to replace the HEPA filter, which is important to maintain its maximum cleaning potential. This air purifier comes with a remote control as well, which makes its operation more convenient.
