Ventilation is the simplest and most convenient method in in addition to formaldehyde. Before you go to in addition to formaldehyde indoors, you can open all the doors and windows at home and ventilate for several hours to see if the indoor air can be better. Then make a plan about in addition to formaldehyde. Ventilation is the effective in addition to formaldehyde way now.

2, green plants, activated carbon

Green plants and activated carbon are also in addition to formaldehyde methods that people often use now. Green plants and activated carbon can purify the air and adsorb harmful substances to some extent, but the adsorption capacity is always limited, which is still useful for small indoor spaces, but the effect can be said to be very weak for some large indoor spaces.

3. Air purifier

The principle of most air purifiers is to physically filter indoor air. Polluted air enters the machine through the air inlet, and after being filtered by the filter screen, clean air is discharged from the air outlet. The filter screen of air purifier can only adsorb and filter, but can't decompose formaldehyde. Therefore, it is ok to have pollution particles in the air, except formaldehyde, you still need to be cautious.

4. Photocatalysts outside in addition to formaldehyde

In addition to formaldehyde photocatalyst is a kind of photocatalyst, which can catalyze the rapid reaction of formaldehyde. If we want to decompose formaldehyde, we still need ultraviolet rays with a wavelength below 400 nm to catalyze the decomposition of formaldehyde. In order to truly achieve the effect of in addition to formaldehyde, we need to consider its products and technology.

5. Fresh air system

Fresh air system is an effective in addition to formaldehyde way now. The fresh air system discharges harmful substances such as indoor formaldehyde, which is very effective. Unlike the effect of an air purifier, it just circulates indoors. If you want to be effective in in addition to formaldehyde, this method is still effective.
