Oransi Air Purifiers
Where should I place my Oransi Air Purifier?
Placement of the air purifier - depending on what you primarily want the air purifier to filter:
- if mainly for outside origin pollen, dust, chemicals and pollutants - place it anywhere in the living room space area, maybe about one third to half the way along any long wall for optimal room air purification. But if a
window needs to be open (outside pollutant entry point), place it nearer to the window to best filter the pollen, etc nearer the pollutant entry point.
- if mainly for filtering air from internal source pollutants of concern e.g. dust mite allergens, fungal spores, pet dander, respiratory virus and other microbes (e.g. COVID, influenza, etc), smells, smoke and volatile organic compounds ('VOCs', adsorbed by Oransi’s activated carbon filter) e.g. formaldehydes, etc from paints, wall boards, synthetic carpet/coverings,
etc) the air purifier can be placed anywhere in the room space, but if an external window is open then place it further away from the opened window.
What is the relevance of ‘CADR’ and why is it such an important measurement?
Clean Air Delivery Rate (CADR) is the volume of air that passes through the air purifier AND is totally (99.9%) filtered every time the air in that room passes through the filter The Oransi Air Purifiers are independently rated and verified (USA Standard, CADR - Clean Air Delivery Rate) to give the rated specified room area for that the particular model of air purifier that can totally (99.9%) clean or purify the air of all particles two times per hour on high speed. The Oransi Mod totally purifies the air of 121 sq metres floor space (of a room 2.4m high) twice per hour on high. That is a room 10m x 12m by way of example, which is large - this is a high quality, high specification air purifier. A room half this size (e.g. 5m x 6m) will filter all the air four times per hour, etc.
How noisy are the Oransi Air Purifiers?
The Oransi Mod noise levels are very quiet compared to most air purifiers of this specification size coverage: 20dBA on low, 49dBA on high. The noise is an airflow related noise sound rather than a motor sound so is quite a low, relatively quiet noise rather than annoying. Unless someone with a respiratory virus infection is present - then the more air changes per hour (ACH) in that room the better - then the speed can usually be reduced to low or medium, and quieter still:
- 'A whisper is about 30 dB, normal conversation is about 60 dB, and a motorcycle engine running is about 95 dB. Noise above 70 dB over a prolonged period of time may start to damage your hearing. Loud noise above 120 dB can cause immediate harm to your ears' CDC US Govt.
- 55 dB is a level that describes moderate to soft sounds. In fact, it is comparable to a quiet home environment, a residential street, or a normal conversation between two people.
How often should I run my Oransi Air Purifier?
Running on ¼ speed 24/7 will generally offer you the most effective method of obtaining a perfect clean air environment ongoing.
Do Oransi Air Purifiers consume a lot of energy?
No, the power consumption on high- speed is only 82 watts, and even less on lower motor speeds.
Which size Oransi Air Purifier should I purchase?
This depends on the size of the room you wish to purify the air. To run in a bedroom the Mod jnr would be ideal but for larger spaces such as combined living and kitchen areas we would recommend the Oransi Mod. For adaptability and ‘value for money’, the Mod is significantly better value on specifications.
Are the Oransi Air Purifiers hard to maintain?
No, we recommend you consider easily removing the 3-in-1 filter unit every 3-4 months, much less often if little carpet fluff or pet dander present, and run a wet cloth or a vacuum down the ‘pre filter’ mesh to remove any excess fluff/dander. Apart from that there are no other maintenance requirements.
What warranty do you have for the air purifiers?
We offer a 10 year warranty for all our Oransi models. All other competitor products offer 6 months to, at best, 3 years warranty. Oransi use very reliable German motors. Quiet and robust, which allows the unprecedented 10 year warranty.
