AirFanta Room Air Purifier B2B Trial FAQ

This B2B trial is open to all kinds of premises (including but not limited to offices, preschools, clinics, restaurants, etc) located in Singapore. All types of businesses (sole proprietorship, partnership, private limited company, etc) and organizations are welcome to apply.

Note: The trial is limited to one location per business/organization.

1. Form submission and verification
2. Scheduling an on-site visit for the indoor air quality (IAQ) check
3. On-site visit for IAQ check and first IAQ report
4. Signing of B2B trial contract
5. Installation of air purifiers at the location and second IAQ report

Yes. AirFanta room air purifiers are not just highly cost effective and powerful, they are also highly energy efficient and take less space than other air purifiers. The AirFanta room air purifiers in this trial can run alongside the current air purifiers, or they can be switched off/replaced. It’s up to you to decide.

Participating in this trial will allow you to experience the difference between AirFanta’s room air purifiers and other air purifiers, as well as the difference that comes from following ASHRAE standard 241 and/or Singapore NEA recommendations for sizing of room air purifiers.

You will be given an indoor air quality report that contains a comprehensive cost, performance, and energy breakdown between AirFanta’s room air purifiers, your air purifiers, and other products in the market,

We measured the air quality of various businesses and organizations in Singapore that use and do not use air purifiers. We found that the biggest issue with all of the businesses and organizations that are using air purifiers is that they were not delivering sufficient clean air.

For example, a business was using around two white label air purifiers in each room, with a total Clean Air Delivery Rate (CADR) of 128 m³/h at low speed. Most of the white label air purifiers were turned off. We measured the air quality levels and found that the PM10 level was around 25 ug/m³ in the room with those air purifiers, and around 40 to 50 ug/m³ in other rooms where they were turned off. These levels were unacceptable as there is no safe limit for PM10 specified by any authority (in other words, they should be kept as close to zero as possible).

According to ASHRAE standard 241, based on the number of occupants using that room and the type of space, the minimum amount of clean air required was around 1,100 m³/h. The white label air purifiers were only delivering 10% of the requirement, which explained the PM10 levels we observed.

After installing two AirFanta 3Pro units in the room to meet the required amount, the PM10 concentration in that room was reduced by 92% to 2 ug/m³. Other rooms saw similar reductions between 75% to 95%.

The business in question also received an indoor air quality report outlining the upfront cost, running cost, and number of units required by different types of air purifiers to meet ASHRAE standard 241. AirFanta’s offerings were the most cost-effective in terms of upfront and running costs, delivered the most clean air per dollar, were far more energy efficient, and generated less noise than others.

For reference, a similar setup to meet ASHRAE standard 241 for the business cited in the example would cost almost S$40,000 upfront with a high performance air purifier manufactured by a famous Japanese brand, but with AirFanta 3Pro (which delivers roughly the same amount of clean air as the Japanese air purifier), this setup would cost less than S$5,000, helping the business to reap huge savings while enjoying highly clean air.

We will use ASHRAE standard 241 or Singapore NEA recommendations to calculate the required number, whichever is higher.

For ASHRAE standard 241, the number of air purifiers will be calculated according to the type of space and number of occupants using the space.

For Singapore NEA recommendations, the number of air purifiers will be calculated according to the total floor space of the location at 6 equivalent air changes per hour.

We will only supply the High Efficiency filter for all B2B trials.This covers most airborne pollutants such as viruses, allergens, dust, smoke, pet dander, pollen, and PM2.5.

The High Efficiency + Activated Carbon filter option, which traps the same pollutants as the High Efficiency filter as well as odors, formaldehyde, new paint smell, haze/tobacco smoke odor, and other chemical smells, is not available for B2B trials. Please consider purchasing or leasing this filter option outside the B2B trial.

If your business/organization is satisfied with the air purifiers, you can continue using them by signing a lease contract (minimum 5 units of AirFanta 3Pro) or purchasing the equipment. Otherwise, the equipment must be returned in good condition to dokuki by the end of the trial contract.

Yes. Low PM2.5/PM10 levels do not mean that the risk of infection is low, because airborne viruses such as COVID-19 and influenza can inhabit aerosols of different sizes from 0.1 microns to 10 microns. We have previously been told by some of our clients that they had to deal with superspreader outbreaks and/or sick building syndrome despite having PM2.5 and PM10 levels close to zero.

The difference in PM2.5 and PM10 levels before and after air purifiers are installed could be used as a gauge to figure out how the infection risk has reduced or increased.

AirFanta room air purifiers are currently being used in residential and commercial spaces in Singapore and all over the world, including but not limited to offices, clinics, schools, universities, retail stores, and restaurants.

Yes. AirFanta room air purifiers are solely powered by mechanical filtration, which does not produce or emit harmful pollutants. Mechanical filtration works by pulling air through fans and filters, a highly reliable and proven technique used for decades by companies and countries all over the world.

All air purifiers from AirFanta do not include components that are potentially dangerous to health, such as ionizers and ozone generators.

On average, AirFanta room air purifiers have a CADR (Clean Air Delivery Rate) that is 3 to 9 times higher than models from other brands in the same price range (S$150 to S$300 suggested retail price). The main reason is because there are four filters taking in air from four sides, allowing the AirFanta room air purifier to clean and move air much faster than air purifiers that only have a single air inlet.

Furthermore, this highly optimized design provides other benefits, such as lower upfront and running cost, low energy consumption, low noise levels, and a compact size.
