As i know air purifier is totally different from air humidifier.

An air purifier or air cleaner is a device which removes contaminants from the air in a room. These devices are commonly marketed as being beneficial to allergy sufferers and asthmatics, and at reducing or eliminating second-hand tobacco smoke. The commercially graded air purifiers are manufactured as either small stand-alone units or larger units that can be affixed to an air handler unit (AHU) or to an HVAC unit found in the medical, industrial, and commercial industries. Air purifiers may also be used in industry to remove impurities such as CO2 from air before processing. Pressure swing adsorbers or other adsorption techniques are typically used for this.

A humidifier is a device that increases humidity (moisture) in a single room or an entire building. In the home, point-of-use humidifiers are commonly used to humidify a single room, while whole-house or furnace humidifiers, which connect to a home's HVAC system, provide humidity to the entire house. Medical ventilators often include humidifiers for increased patient comfort. Large humidifiers are used in commercial, institutional, or industrial contexts, often as part of a larger HVAC system.

Based on consumer condition which they want to choose. If want remove those contaminants that will cause sore throat or cough then is air purifier. If want to add moisture or increase humidity to the dry air then is the function of humidifier.

So far i think there is no any website that specific can compare this two different brand air purifier. But you can go here https://www.allergyuk.org/get-help/products...ifiers#products as it can compare many types of air purifier based on the requirements that consumers need as it endorses certain products that restrict or remove high levels of allergens and gives them a Seal of Approval. (Allergy UK)

Inside still mention that, some odor ingredients absorbed by the filters may become separated and may be discharged through the air outlet and result in additional odor. Depending on the usage environment, especially when the product is used in a condition significantly more severe than household use, this odor may become strong in a shorter period than expected.

The air purifier is designed to remove air-suspended dust and odor, but not harmful gases (for example, carbon monoxide contained in cigarette smoke).

If the odor sources still exist, it cannot completely remove the odor (for example, odors from construction materials and pet odors ). It is suggested to open the window a bit when you are smoking in order to facilitate ventilation. In this case we recommend purchasing the optional replacement filter.

Then what is the purpose still purchase this air purifier ah?

What is the price and how long it need to change the filter? The maintenance cost how much?

Why home no need change the filter? It may lose it efficacy since the filter will dirty for so long time.

Some filter have the monitor light and signer tell you that when to change the HEPA and when to wash the pre-filter by our own. But still need to see filter brand, not every brand also like that i think.

Wonder its really can last 10 years? Hmmm....

Which brand did you refer ?

I am not consider the maintenance cost actually. Is seeking is it the air purifier can work function well effectively since it filter only need change 10 years once.

If the air purifier is lost maintenance cost but at last not really work it efficacy then macam lost the function already.

I have one unit of Atmosphere but not sharp AP inside my dad room coz his room really full of dust that we cannt see it as he cannot sleep well. Now so far so good the room does not contain any weird smell. So it is quite good for me. The main is when it turn on turbo speed there is no noisy sound as other, the turbo speed able to clear and clean the air in up to a 390-square-foot room in a short time and very save electric.

I see the light up to determine whether the filter need to wash (pre filter) or change (HEPA filter). But it is based on the air condition, if is haze then need to wash the pre-filter like air cond.As the picture below.

Then how if the sharp AP filter discontinued after 10 years since 10 years so long time?

A humidifier is a device that increases humidity (moisture) in a single room or an entire building, provide humidity to the entire house. Medical ventilators often include humidifiers for increased patient comfort. Overuse of a humidifier can raise the relative humidity to excessive levels, promoting the growth of dust mites and mold, and can also cause hypersensitivity pneumonitis (humidifier lung).

A dehumidifier is generally a household appliance which reduces the level of humidity in the air , usually for health or comfort reasons, or to eliminate musty odor.

Based on what condition you need, if always in an air cond room and feel uncomfortable due to too dry of the environment , then humidifier is the choice. If your house or room is humidity or full of dust that we hard too see by using our eye , sometimes got pets' fur, or odor , you can use dehumidifier or air purifier to reduce the contaminants in the air and feel comfortable with fresh air .

Dehumidifier is to reduce the humidity in your environment like you feel your room or house very humid (潮湿） , means water vapour is high in the air thn u need the dehumidifier. Dehumidifier does not have storage behind i think, that is humidifier as it need to humidity the room so may have a small water storage behind or inside. The water in that thing is not contaminants.

Contaminants （污染源）is means that those dust or dirty things that we are unable to see by using our eyes . It may contain in our air or environment. Like pets' fur, dust, cigerette smoke, dust of haze an so on that some ppl will feel uncomfortable on it and may be will cause health problem. So that,air purifier （空气净化器）is another use to absorb those contaminants and reduce the dust or those thing in the air, to let us have more fresh air.

How much for that?

So this one each year need service one? Cannot self wash the filter?

The service fee not cheap leh.

What air filter need every year change the filter, it really expensive, even though the best one Atmosphere also change once 3-5 years, depends on the environment.

Try go to this website to filter see what allergy you want to filter. It is the third party website in uk that have cert on it.
