# OUNEDA ZY3866G Air Purifier, H13 HEPA, 2300 sq ft

The OUNEDA ZY3866G air purifier is listed for rooms up to 2300 sq ft and combines a multi-function HEPA filter with PM2.5 monitoring and touch controls. Auto mode, sleep mode and a child lock offer flexible operation, while the large stated coverage area and limited independently substantiated performance data make room-size suitability worth checking carefully.

## Before you buy

- Listing details are inconsistent: the title claims H13 HEPA, while the technical filter field says “Multi-function Hepa Filter”. Room coverage is stated as 2300 sq ft, but the claimed up-to-three air changes per hour has no accompanying CADR or room-height detail. The 22 dB noise figure is specifically attributed to sleep mode, not all settings. Check the selected listing and filter replacement compatibility before buying.

## A good fit for

- Buyers seeking an air purifier with a PM2.5 display, auto mode and touch controls.
- Homes with pets or concerns about dust, pollen, smoke and odours, based on the listed filtration targets.
- People who want a sleep mode, child lock, timer and aromatherapy pad.

## Less suited to

- Buyers who need a substantiated CADR or independently verified room-coverage performance.
- Buyers who require confirmation that the supplied filter meets a specific H13 standard.

## Customer feedback

Customer feedback highlights perceived effectiveness, fresher-smelling rooms and improved air quality, including a report of help with cigarette smoke. Customers disagree about noise. For buyers considering the listed 22 dB sleep-mode claim, that mixed noise feedback makes listening expectations and chosen fan setting relevant. Feedback is limited and does not verify the stated room coverage or filtration specifications.
- Positive themes: Customers describe the purifier as effective and say rooms smell fresher and cleaner.
- Positive themes: Some customer feedback reports positive experiences with cigarette smoke and air quality.
- Mixed feedback: Customers disagree about the noise level.

## Frequently asked questions

### How large a room is this purifier claimed to cover?
The listing states 2300 Square Feet and says it can refresh air up to three times per hour. It does not provide a CADR figure or the room-height assumptions behind those claims.
### Does it have an H13 HEPA filter?
The title claims H13 HEPA, but the technical details identify the filter as “Multi-function Hepa Filter”. Confirm the exact filter specification for the selected listing.
### What controls and modes are listed?
The listing describes touch controls, auto mode, three fan speeds, a switchable display, a child lock and 2H/5H/8H timer settings. It also claims sleep mode.
### What do customers report about it?
Customer feedback describes effective air cleaning and fresher-smelling rooms, while noise experiences differ. These reports are subjective and do not establish coverage or noise performance across every setting.
