1. We remove Virus and Bacteria with 99.99%
The Claim: Our Air purifier removes 99.99% of the virus and bacteria
The Advice: Double check the function of the cleaner and verify their test certificates as this might be a misleading statement as the removal of and at time killing of virus and bacteria only happens in the air purifier for most manufactures, meaning it is only the air that passes the cleaner that is cleaned, the remaining room and surfaces still contains bacteria and virus that stick to wet surfaces.
Note 1.1. To remove virus and bacteria effectively and actively from the room it needs to be cleaned and ventilated well or as alternative a safe amount of Ozone can be added to actively kill bacteria and virus in the room.
Note 1.2. To measure effectiveness of Bactria and Virus removal, the manufacturer needs to have the device tested by a certified laboratory that can provided controlled environment and documented swap testing. There is currently no devices that can concurrently measure bacteria and virus the air or room.
2.Purification or filter performance is 99.99%
The Claim: Our high efficient Hepa or Merv filters with 99.99% efficiency
Advise: Most air purifier manufactures purchase the Hepa or Merv filters from a sub supplier, it is therefore important to check if it is only the filter that is tested or the whole air purifier as there can be leaks in the connection between air filter and air purifier body.
Note.2.1. Hepa and Merv filters only traps and does not kills Virus and Bacteria, there could be a possible bio-hazard in replacing the filter as well as a disposal fee.
3.We remove dust in the room.
The Claim: We reduce the dust in the air and room
The Advice: Dust in the air comes from outside, if you have a closed house and clean the house regularly you have a very small amount of dust in the air, so you do not need to remove dust unless you have a dust creating source in the house.
Note 3.1. Residential homes do typically not have dust creating sources, they are normally only found in industrial plants, workshops, clinics etc and a at capture at source is required such as a extraction hood and dust collector.
Note 3.2. Pollution sources in a residential home is typically mold spores from mold attacks, organic particle from cooking, people, and animals as well as bacteria, these particles are best removed by building machinal ventilation, opening windows to replace air or where that is limited safe proving a small amount of Ozone by UV-C
4.Credibility, our device is tested.
The claim: The air purifier is certified tested but often the manufacturer only posts a picture of a test report or just refer to a certificate number but there are no details of who have done the test and what the test reveals.
Advise: Please ask your suppliers for the test certificate properly if they are not readily available and please check details carefully. Normally there is a summery from the test institute declaring the purpose of the test and performance achieved and read disclaimers properly.
5.High air flow capacity (CADR)
The Claim: We can clean a very big room or house as we have a very big air purifier / air cleaner that can deliver xxx of air per hour also known as Clean Air Delivery Rate (CADR)
The Advice: Several small air purifiers are better as the risk of dead spots in the room are reduced. Ask any ventilation expert and they will tell you that to properly control and clean air in the room you need to have several outlet/inlet vents, a good sample is to look at how many aircons are used in a restaurant, office, or conference room.
Note 5.1. Air purifiers have a limited reach and ability to circulate air, to provide efficient air cleaning we recommend placing the air purifier App. 2 m above floor level, if possible, as most contaminated is in that level and most people breath the air in same level. If bigger rooms a central air cleaning system should be installed or more air purifiers installed.
