Can onions remove formaldehyde
Onions can not remove formaldehyde. Because onions can not remove formaldehyde, it does not have this effect. The reason why people will produce onions can remove formaldehyde this idea, because the onion will be placed in the newly renovated indoor, the onion itself strong flavor can cover up the taste of formaldehyde, resulting in people mistakenly think that onions can remove formaldehyde, but in fact it is not useful at all. And formaldehyde is a toxic irritant gas, even if formaldehyde is very easy to dissolve in water, but the water content of the onion is not high, can not play the effect of formaldehyde.

To effectively remove formaldehyde also need to use the correct method, such as window ventilation, activated carbon adsorption, green plant purification.

Ventilation deformaldehyde is a simple, practical and cost-effective method, this time just need to open all the windows and doors, you can choose to use the floor fan as an auxiliary, open the oscillating mode, aimed at the window blowing, to achieve the wind through the hall, so that the indoor and outdoor air exchange maximum efficiency, so that formaldehyde flavor faster dissemination. And the circulating air also helps the air purification products to play their own adsorption role.

Greenery is mainly the use of plants can absorb indoor air pollution purification of indoor air, or the use of micro-organisms, enzymes for biological oxidation, decomposition. Green plants can use formaldehyde as raw material for photosynthesis, and successfully decompose formaldehyde. Green plants in formaldehyde processing speed faster in addition to green, hanging baskets, Boston kidney fern, chrysanthemums, green-leaved dragon's blood tree, etc., these plants are NASA experts recommended plants, can be absorbed through the leaves, degradation of formaldehyde. Placing some green plants in your home serves to remove formaldehyde while also beautifying your living room environment, which is the best of both worlds. Although plants can adsorb formaldehyde, but the adsorption capacity of plants is limited, relying on plants alone to remove formaldehyde is not realistic, which can only play a supporting role.

Activated charcoal purifies the air by relying on the developed pore structure and surface area of the charcoal itself, which can be largely exposed to the surrounding air and passively adsorb some pollutants into its own pores. The advantage of activated carbon is that it is also relatively affordable. But activated carbon can only adsorb formaldehyde and other harmful gases can not be decomposed, adsorption and filtration in limited conditions, very easy to adsorption saturation caused by secondary pollution, the use of a month's time will need to be replaced with a new one.

While the air purifier has an internal filter, when the purifier is running, it can adsorb formaldehyde in the air and release fresh air to achieve the effect of removing formaldehyde. When in use, not as soon as you open the purifier can immediately purify the air, it needs a process, so we want to have a good indoor air, it is best to open in advance.

Some good purifiers will automatically rest and stop running when the air in the room reaches a certain level, so our repeated switching on and off the machine will damage the life of the purifier. And note that when we turn on the air purifier, it is best to make sure that the ventilation of the room is not very obvious, otherwise it will directly affect the purification effect of the machine.
