APEX+ Aero Smart Air Purifier

A smart H13 HEPA air purifier for Singapore bedrooms, studies and home offices. The APEX+ Aero combines a published 300m³/h CADR, H13 True HEPA filtration, activated carbon, a PM2.5 sensor and app control in a compact 24.4cm footprint. It is supported locally by ULTI Singapore.

APEX+ Aero at a glance

CADR is the product's published clean-air delivery figure. The listing does not identify it as AHAM smoke CADR. The supplied specification lists noise at ≤55 dB but does not give a sound level for each fan speed.

Technical specifications

Which room is it suited to?

Choose an air purifier by the volume of the room you will actually close and clean. Multiply room length by width by ceiling height to find cubic metres. Dividing 300m³/h by that volume gives a useful, simplified comparison of clean-air delivery per hour.

These are calculations from the published CADR, not room-test results. Doors, windows, furniture, ceiling height, purifier position and fan speed all affect real performance. For haze, Singapore's NEA guidance uses smoke CADR and recommends a value at least three times room volume. Because Aero's published number is not identified as smoke-specific, ULTI does not present the table as a haze certification.

See the Singapore haze, CADR and room-sizing guide for the full calculation.

H13 HEPA and activated carbon

The advertised filter combines two different jobs. The H13 HEPA stage is designed to capture airborne particles from air passing through the filter. The activated-carbon stage is included to help with selected odours and gases. A filter-efficiency percentage is not the percentage of all particles removed from an entire room; airflow, sealing, run time and room conditions still matter.

For homes with cats or dogs, the purifier can form part of a routine for airborne dander and selected odours. Continue vacuuming, washing pet bedding and removing the source of smells. Read the pet dander and odour guide before choosing a position around pets.

Smart controls for everyday use

• PM2.5 sensor: reads fine-particle conditions near the purifier.
• Automatic mode: adjusts operation in response to the particle sensor.
• Wi-Fi app control: lets you check and adjust the purifier from your phone.
• Timer: schedules operation around work, sleep or time away from the room.

A local PM2.5 reading is not the same as Singapore's outdoor PSI, and it does not measure every gas, smell or allergen. Use the display as an operating aid rather than a medical or whole-home air-quality diagnosis.

How to place and use the Aero

1. Put it in the room where you spend the most time, on a stable and level surface.
2. Keep the air intake and outlet clear of curtains, bedding, walls and furniture.
3. Close the room during haze when outdoor conditions are poor, following current NEA advice.
4. Run a suitable fan speed consistently instead of relying on brief bursts.
5. Re-open doors or windows for ventilation when outdoor air improves. An air purifier filters recirculated air; it does not supply fresh air.

Filter care and ownership cost

Check the exact replacement filter, its current price and availability before buying any purifier. Filter life depends on use and air conditions, so ULTI does not claim a universal replacement interval for the Aero here. Follow the product instructions and the app's filter information. Do not wash the HEPA or carbon assembly unless the instructions for that exact component permit it.

For the current compatible-filter information, contact ULTI on WhatsApp at +65 8788 8866. Consumable filters are separate from warranty coverage.

Compare before you buy

Air-purifier coverage claims are often calculated with different air-change assumptions, so square-metre figures cannot always be compared directly. Our Aero vs Xiaomi, Philips and Levoit comparison lines up published CADR, dimensions, noise disclosure, filters and smart features in one table.

For a wider market view, use the 31-brand Singapore air purifier comparison. Before ordering any purifier, read the HEPA and replacement-filter buying guide and our plain-English explanation of OEM and private-label air purifiers.

Frequently asked questions

Is the Aero suitable for haze?

It has an H13 HEPA filter and a published 300m³/h CADR, both relevant points for particle filtration. Singapore's haze guidance refers specifically to smoke CADR. The current Aero listing does not identify its 300m³/h figure as smoke CADR, so match the product to your room with that limitation in mind.

Does the Aero remove odours?

It includes activated carbon to help with selected odours and gases. Performance depends on the pollutant, carbon media, airflow and filter condition; it is not a promise to eliminate every smell.

Can one unit clean my whole flat?

Do not assume so. Start with one enclosed room or connected area and calculate its volume. Open doors and corridors increase the space being treated.

Is it quiet enough for sleep?

The Aero includes Sleep Mode and has a specified noise level of ≤55 dB. Sound levels vary with fan speed; the supplied specifications do not give a separate Sleep Mode decibel figure.

What is included?

The purifier is supplied with its H13 HEPA filter assembly and Singapore power adapter. Confirm current package details with ULTI if you need a specific accessory.
