The best Samsung air purifier depends on where you live and how much air the room needs cleaned. Samsung Australia’s listed models range from the 41 m² Essential AX32 to the 90 m² Ultimate AX90; the Bespoke Cube AX53 and AX70 sit between them. These ratings and model codes are market-specific, so check local availability and match the exact model code before buying.
How to choose a Samsung air purifier
Start with the room’s floor area and the purifier’s clean air delivery rate (CADR), then compare features you will actually use. Samsung’s coverage figures and CADR values below are for its Australian lineup; they are not universal specifications for every product carrying a similar name.
- Match the room: choose a model rated for at least the space where it will operate. Do not assume that a purifier’s appearance or series name indicates its capacity.
- Compare CADR: a higher figure indicates more air delivered through the stated cleaning process, but compare figures in the same units and from the same market.
- Check household features: Samsung’s Australian comparison distinguishes pet-oriented mesh filters, sensors, child-care locks, Wi-Fi and SmartThings support across models. Verify the feature list for the specific model code.
- Confirm local availability: regional codes, filters and product availability vary. The Australian lineup is not a global ranking.
Samsung Australia models compared
Samsung Australia’s comparison lists these four models. Coverage and CADR are the comparable measures; model codes and filter codes identify the Australian variants and accessories shown in that comparison.

#1 Best Overall
- SUPERB FILTRATION SYSTEM WITH NANOFIBER TRUE HEPA: NanoFiber True HEPA filter traps on average 99.97% of particles 0.3μm* in size.
- THREE LAYERS OF FILTRATION: In addition to the fine particles captured by the NanoFiber True HEPA filter, a removable pre-filter helps capture larger particles and an activated carbon filter helps keep the air smelling fresh. Together, these three filters work in concert to enhance your indoor air quality.
- PM 1.0 SENSOR: The micro particle sensor inside the LG PuriCare 360 detects particles as small as one microns (PM 1.0), for more effective filtration. Enhance home comfort by efficiently eliminating most of these microscopic particles for improved air quality.
- SMART INDICATOR - KNOW THE AIR QUALITY, RIGHT NOW: The intelligent LED indicator system atop the LG PuriCare 360 changes from red to orange to yellow to green as the indoor air quality improves, a visual indication of its effective performance.
- FILTRATION FOR ROOMS LARGE AND SMALL: From an expansive living room to an office, LG PuriCare 360 provides cleaner air where and when you need it, with coverage for rooms up to 2059 sq. ft. at one air change per hour or up to 429 sq. ft. at 4.8 air changes per hour.
Which model fits which room?
For a larger listed room: Ultimate AX90 or Bespoke Cube AX70
The Australian comparison rates the AX90 for 90 m² and 701 m³/h CADR, while the AX70 is rated for 70 m² and 545 m³/h. Choose between them based on the room size and the actual availability of each regional variant; Samsung’s AX70 page identifies model AX70B9550GN/SA and lists Wi-Fi and SmartThings support.
For a medium-size room: Bespoke Cube AX53
Samsung Australia lists the AX53B9350GN/SA at 53 m², 413 m³/h CADR and 42 W power consumption. The product page describes a multi-layer system and lists pet-related features, sensors, Wi-Fi and SmartThings support. These details apply to that Australian variant, not automatically to every AX53-branded product.
For a smaller listed room: Essential AX32
The Australian comparison rates the AX32 at 41 m² and 320 m³/h CADR and gives its compatible filter as CFX-K100/GB. Check the country-specific product listing before treating these specifications or filter code as applicable to a unit sold elsewhere.
Rank #2

- SEE YOUR AIR IMPROVE: With CleanSense IQ, watch the display as your air quality adjusts in real time. No guessing your air quality––just fast, visible results. "Clean Air 100%" indicates that airborne particle concentration (PM 1.0–10) is at or below the sensor’s detection limit, not that the air is free of all pollutants.

US model example: AX26BG3100GG
A Samsung-hosted US specification sheet dated 2022 lists model AX26BG3100GG for 260 sq. ft., with CADR values of 168 for tobacco smoke, 180 for dust and 180 for pollen. The sheet reports 99.97% dust collection efficiency for 0.3 μm particles under its specified test method. That is a filter-media result, not a claim that the whole appliance removes 99.97% of all pollutants in a room or guarantees a health outcome.

Replacement filters and upkeep
Match the filter to the full model code
Filter compatibility is model-specific. Samsung US lists CFX-K1001/AA for AX26BG3100GG and says that filter cannot be washed for reuse. Separately, Samsung US lists CFX-H1001/AA for Cube models AX300T9080S/AA and AX300T9080W/AA. These are US accessory examples, not universal Cube or Bluesky filters; do not substitute them for the Australian CFX-C100/GB or CFX-K100/GB codes listed above.
Before ordering, read the model code on the appliance and check the filter code in the matching local Samsung listing or manual. Similar series names are not enough to establish compatibility.

Rank #4

- [Filter Alerts] The air filter indicator tells you when the filters need to be replaced, and the pre-filter needs to be cleaned for maximum efficiency, based on how much air they have processed
Use the replacement interval as guidance, not a guarantee
Samsung Australia says filter life depends on room air quality and operating time, and gives 6–12 months as an expected replacement interval when the purifier is not running 24/7. Check the manual and filter indicator for your exact model; a fixed calendar interval may not reflect your conditions.

Buying decision
For the Australian models documented here, shortlist by required room coverage: AX32 for a listed 41 m², AX53 for 53 m², AX70 for 70 m², or AX90 for 90 m². Then verify the exact regional model, desired controls and pet-related features, and compatible filter before purchase. If shopping in the US, treat the AX26BG3100GG figures and US filter SKUs as a separate model-market example rather than interchangeable entries in the Australian lineup.
