Today’s featured air purifier comes from the Renpho lineup. This purifier is larger than the more compact Renpho air purifier, but is also able to treat over 3 times the amount of area coverage.

It has some upgrades to the body style as well, but how will it stand up in the performance category?

Let’s dive in and find out now.

A Larger, Budget Air Purifier


Renpho Air Purifier

Air intake is located on the sides of the unit and output is at the top.

The Controls

Settings and controls on the Renpho can be adjusted using a variety of touch controls on top of the purifier.

The control functions include:

  • Power: turn the purifier on or off
  • Speed: adjust from 3 manual speeds or set to auto
  • Sleep mode: dims the lights and runs the purifier at a quieter decibel level
  • Timer: set a time for 2, 4, or 8 hours for limited use
  • Lock: locks the controls so settings cannot be adjusted by a small child
  • AQ: this feature allows the unit to automatically check the air quality and adjust setting as needed, based on quality
  • Filter: lets you know when it’s time to replace the filters

Smart Mode

The Renpho has the ability to auto-detect indoor air quality. When the sensors notice that the quality has dropped below and acceptable level, it will automatically change fan speed until levels stabilize.

The sensors communicate the air quality using changing LED colors:

  • Red: poor air quality
  • Yellow: moderate air quality
  • Blue: good air quality

Quiet Mode

When in Quiet Mode, the Renpho air purifier dims all the lights on the unit and operates at a lower decibel level (around 35 dB).

In turn, the lower noise level and dimmer lights make it easier to not be disturbed if you’re running this purifier in a bedroom while sleeping.

How does it clean the air?

The Renpho cleans the air by using a 4-stage filtration system. The multi-phased approach helps it address multiples types of particulate, like dust, mold, allergens, pet dander, and even smoke.

Here is the detailed run down about the role of each filter:

  1. Pre-filter: captures large debris like pet dander and hair
  2. Charcoal filter: absorbs large particulates, like dust mites and lint
  3. Activated carbon filter: helps reduce household odors, from cooking smoking, or pets
  4. HEPA filter: removes up to 99.97% of other finite airborne particulate and bacteria

How big is the Renpho?

The Renpho air purifier is a medium-sized air purifier.

Exact dimensions of the Renpho are as follows:

  • 14″ wide
  • 8.1″ deep
  • 20.9″ tall

This purifier can treat rooms up to 300 square feet, making it a solid option for living rooms, master bedrooms, game rooms, or other open area spaces.

If you plan on moving this purifier around to various rooms in your home, you may be wondering on the weight of this purifier.

The Renpho air purifier weighs 15.8 pounds, about the weight of an upright vacuum cleaner.

Using the Renpho

Setting up and using the Renpho is straightforward. There is no smart control or apps to set up.

To setup the Renpo purifier the first time:

  1. Unbox the unit.
  2. Remove all packaging.
  3. Make sure all filters are installed properly.
  4. Turn the unit on.

From here you can either adjust fan speed manually or set it to auto mode.

In auto mode, the Renpho air purifier will use sensors to detect indoor air quality and adjust settings automatically as needed.


Maintenance of the Renpho air purifier basically comes down to checking the filters and replacing when necessary.

Regular replacement of filters keeps the purifier sensors and filtration working at peak performance.

Renpho Performance

The main job of any air purifier is to purify the air. Was Renpho the best air purifier we’ve tested to date? No.

However, it was reasonably priced and has a few perks.

What were the results?

Starting Baseline

  • PM2.5: 4.5
  • PM10: 8.5
  • Particles: 214
  • AQI: 19

After 1 Hour

  • PM2.5: 1.1
  • PM10: 1.7
  • Particles: 99
  • AQI: 4

After an hour, the Renpho air purifier only removed 53.74% of air particles from the medium-sized room we tested in (~12×12′). It was able to improve PM2.5 air quality by 75% and overall indoor air quality (AQI) by 79%.

Is the Renpho a Good Value?

All things considered, is the Renpho AP0001 a good value? It has a number of noteworthy features, like:

  • Auto mode
  • Sleep mode
  • Variable fan speeds
  • 4-stage filtration
  • Good area coverage (up to 305 sf)

But under the hood, performance wasn’t as impressive as we would expect.

It certainly improved the air quality, without a doubt, but I would have liked to see a little better number from any purifier designed to clean large spaces, like the Renpho.

NOTE – Oddly, the smaller more compact RENPHO air purifier performed better in our tests, reaching PM2.5 of 0.7, PM10 of 1.0, and AQI of 0. You can see that RENPHO review here.

Should You Buy the Renpho?

Features, specs, performance, and usability aside, the question remains, should you buy the Renpho? It’s reasonably priced, a decent performer, and has a few good bells and whistles.

That said, The Renpho AP001 sits in a weird spot with respect to performance vs. price. There are a number of competing HEPA-based air purifiers that offer better purification performance (based on our tests) at a similar price point.

As a result, it’s hard to recommend the Renpho over those options.

The Renpho isn’t a bad purifier by any stretch, there are just better options on the market for the money.

I would recommend the Renpho AP0001 if you 1) like the Renpho brand, 2) catch it on a great sale, and 3) want the following features a purifier.

  • Smart sensors – If you want a purifier that can automatically detect indoor air quality and adjust as needed, the Renpho fits the bill. This feature takes the guesswork out of knowing what speed to set.
  • 4-stage filtration: If you’re looking for a purifier that has a wide range of filters, including carbon and charcoal, which can help reduce the presence of odors.
  • Sleep mode – If you need an air purifier that can run at a lower sleep setting and with dim lights, the Renpho is another excellent option.

An Okay Option
  • Design - 93%
  • Performance - 91%
  • Quality - 93%
  • Usability - 94%
  • Value - 85%


The Renpho AP001 air purifier is an okay air purifier with good area coverage (approx. 300 aq st), auto control, and decent performance. It is taller and slimmer than other competitive air purifiers which could make it an attractive option, depending on the kind of space you are hunting for. It’s performance left something to be desired in our air purification tests, but it did still improve air quality to a PM2.5 level of 1.1, PM10 of 1.7, and AQI of 4.
