USE THIS AIR PURIFIER ONLY FOR ITS INTENDED USE AS DESCRIBED IN THIS MANUAL. ANY OTHER USE NOT RECOMMENDED BY THE MANUFACTURER MAY CAUSE FIRE, ELECTRIC SHOCK, OR INJURY TO PERSONS.
TERMS USED IN THIS GUIDE
CADR: The "Clean Air Delivery Rate", or CADR, describes the air purifier's effectiveness based on the volume of clean air produced per minute.
dB (A): Decibels are units that measure sound intensity. For example, 25 dB is commonly described as quiet as a "whisper" or "library quiet".
HEPA-13: HEPA, or high-efficiency particulate air, is a standard to designate the efficiency of an air filter for removing particulates. HEPA-13 filters provide particulate filtration removing 99.97% of particles over 0.3 microns in diameter. These include pollen and other fine particulates.
Pre-filter: A pre-filter removes larger particles before the air is passed through the HEPA-13 filter. Renew has two pre-filters: an audio-grade textile outer pre-filter and a mesh inner pre-filter. Both can be cleaned and help to extend the effective life of the HEPA-13 filter.
Activated carbon: Sometimes referred to as charcoal filters, these filters use activated carbon pellets that absorb and trap gasses and odors from the air. Among many other things, this filter helps to address the odors that can come from pets, cooking, and smoking.
PM_1/PM_2.5/PM_10 : These are designations that describe airborne particulate matter (PM) types in terms of their maximum diameter as measured in microns ( ). All of these are inhalable, but PM_2.5 particles are notable for being small enough to not only enter the lungs but also the bloodstream. Long-term exposure to air with high levels of PM_2.5 has been linked to several serious long-term health effects including heart disease and lung disease.
The high-precision PM sensor in Renew measures the concentration of particulates in the room's air and reports PM_2.5 levels in the Airthings app in terms of microns per cubic meter of air ( /m^3 ).

STEP 3. Connect to WiFi
Download the Airthings app and follow the instructions to create an account, connect to your WiFi, and add Renew to your account. If you already have an Airthings account, tap Add device to add Renew and you're ready to go.
To disconnect from WiFi, go to the device settings in the app, or see instructions in this manual to "factory reset.
Note: For WiFi connectivity, Renew requires a 2.4 GHz band router and the Airthings app. The Airthings app requirements can be found in the App Store and Google Play.
Getting the most out of your Renew
Renew is designed to fit easily into your environment and offers a few different placement options.

text_image
Upright Upright with air outlet to the side Laid flatHowever you choose to place Renew in your room, we suggest you consider the following to get the best performance.
- Only place the unit on a level and stable surface.
- Don't place anything on top of Renew.
- Renew takes air in through the textile cover and blows it out through the vented surface next to the control panel. Make sure you leave at least 8" (20cm) of free space so that air enters and leaves Renew freely.
- Avoid blocking the flow of air into the particulate sensor. Leave at least 8" (20cm) around the opening for the sensor.
- Operate Renew in an enclosed space to get the quickest results and to operate efficiently.

8 in / 20cm 8 in / 20cm 8 in / 20cmMounting Renew on a wall
IMPORTANT NOTE: Make sure to use screws, drill bits, and fittings that are suitable for your type of wall material and the weight of the unit (13.5 lbs or 6 kg). Correct installation of the wall hook is essential and your responsibility. If you need help or are unsure, please contact a contractor. We do not accept any liability associated with the hanging of the Renew, including damage or injury resulting from incorrect assembly, mounting, or usage or liability due to the unit falling or the hook separating or dislodging from the wall.
Renew can be mounted to a wall using the wall hook provided in the box. On the back side of the unit, there is an opening for this purpose. You should ONLY mount the unit with the textile cover facing out and the air outlets and control panel facing up. Never use the strap handle to hang the unit - it is not designed for that purpose.
We recommend wall-mounting the unit with the bottom side no more than 12" (30 cm) from the floor.
- On the back side of Renew, there's a small covered opening. Remove this cover and save it somewhere you can find it again. We suggest you use the cable compartment cover to store this piece.
- Using screws and other tools suitable for the wall material, attach the wall hook securely to the wall. Make sure the hook is firmly in place.
- Now hang the unit on the hook using the opening on the back side.

Illustration showing three steps of installing or adjusting a device panel, labeled 1, 2, and 3.Set it and forget it with Auto mode
You don't have to worry about when to turn Renew on or off or how fast to run the fan. We designed Renew with a high-precision, laser-based particulate matter (PM) sensor that keeps track of your room's air quality. As soon as it detects an increase in PM, it activates the appropriate fan speed to keep air quality from becoming a problem.
That's why we recommend using Auto mode during daytime hours. You can rely on great air quality while avoiding unnecessary energy use.
Fan safe feature
If Renew detects that the fan speed drops abnormally, the motor will automatically stop to avoid any further damage to the fan blades. This typically happens if items are accidentally dropped or fall into the air outlet grill.
USING THE CONTROL PANEL
The panel comprises a row of indicator lights next to control buttons for common operations. Additional operations can be activated by using a combination of buttons which are also described here.
Silent mode
Runs on the lowest speed for 8 hours with panel lights dimmed.
Child lock indicator
Press Auto and Boost together for 3 seconds to turn child lock on or off.
Air quality indicator
Indicates the room's current air quality in terms of the PM level.
$$ \mathrm{Red} = \mathrm{POOR} $$
(Over 25 g/m ^3 )
$$ \text { Yellow } = \text { FAIR } $$
(10 g/m ^3 to 25 g/m ^3 )
$$ \text { Green } = \text { GOOD } $$
(Less than 10 g/m ^3 )
Filter change indicator
Glows when it's time to replace the filters.
Check the Airthings app for easy ordering.

For manual operation of the 5 speeds.
Boost mode
Runs on top speed for 1 hour.
Auto mode
Set & forget. Adjusts fan speed based on current air quality.
Standby
Turns the purifier function on or off. When off, the air quality sensor continues to operate.
WiFi status
Glows steady when connected to Internet via WiFi. Is off if not connected to WiFi. Blinks if connected to WiFi but there is no Internet connection.
Here are the additional operations you can perform using the onboard control panel:
| Reset the filter change indicator | Do this right after changing the filters. Press and hold the Silent mode button for 5 seconds. This resets the filter algorithm and turns off the filter change indicator light. |
| Turn off button beeps | Press the Boost mode button for 5 seconds to turn off the beeps when the buttons are pressed. Do the same to turn the beeps back on. |
| Dim the panel's LED lights | The LED lights are always dimmed when you activate Silent mode. You can manually dim lights for ALL modes by pressing the Auto mode button for 5 seconds. Do the same to turn the lights back on. |
| Reset the unit to factory settings | Press and hold both the + and - buttons for 10 seconds to factory reset the device. When you factory reset the device all WiFi connections are erased and the device is ready to be paired to a new account in the app. The device will continue to show in your app unless you delete it, but you can no longer see new PM data or access smart functionality. |
MAINTAINING YOUR RENEW
There isn't much to do to keep your Renew running effectively for years. Along with changing the filters as needed, we recommend keeping the unit clean and free from excess dust.
Changing the filters
Renew tells you when to change the filter based on a smart algorithm. This ensures everyday filter efficiency if the air is more polluted than average. The Filter change indicator on the control panel will illuminate. You can also check the remaining filter life in the app at any time.
You can order replacement filters at airthings.com, in the Airthings app, or at selected authorized resellers.
Once you have the replacement filters on hand, here's what to do:
- Unplug the device before changing the filters.
- Remove the textile front cover (outer prefilter) and inner prefilter.
-
Now remove the old filter and replace it with the new one. Remember to insert the new filter with the pull-tab face-up and out.
Tip: Place the used filter directly into the bag the new filter comes in to prevent dust and particles from scattering. -
Reassemble the prefilters and plug the unit back in.
-
Finally, reset the filter change algorithm and turn off the Filter change indicator light. To do this, press and hold the Silent mode button for 5 seconds.
Do not try to touch the fan blades when changing the filters.
Keeping it clean
Before cleaning Renew, it's a good idea to unplug it.
Wipe the outside of the unit with a clean, dry cloth to remove any accumulated dust and dirt. Never use cleaning liquids to clean Renew - if you must, only use a lightly damp cloth. Water or moisture should never enter the unit.
The front cover (also a prefilter) should be cleaned using a vacuum at a very low and gentle speed. Be careful not to push hard on the textile or you risk damaging it.
The mesh prefilter can be cleaned with water and a small amount of mild dish soap. If you have a handheld shower attachment, that's the easiest way to do this. Use a gentle stream of water or submerge the filter and gently move it back and forth. You must let the mesh prefilter dry completely before putting it back in. Moisture can increase the risk of mold growing inside the unit.
