First of all, when you decorate your house, you should choose green decoration materials with environmental protection signs. The big core board shall be made of benzene free diphenyl formaldehyde adhesive; the formaldehyde content of the floor material shall reach the volatilization stability below 0.12ml per cubic meter; the radioactivity of the ceramic tile shall be the radioactivity standard of A-class marble; the coating shall be water-based; the mold steel shall also be produced by the regular enterprise.

　　其次，要充分发挥抽油烟机的功能。无论是炒菜还是烧水，只要打开厨房用具，应带油烟机打开，同时关上厨房门，打开窗户，这样有利于气流，污染物。冲马桶时要把马桶盖放下，不用时尽量不要打开。更好在水箱中使用固体缓释剂，选择有效的空气产品，净化空气。此外，在清洗时，更好使用真空吸尘器，如果可能的话，或使用拖把和湿抹布。假如用扫帚，动作要轻，不要扬起灰尘加剧空气污染。鸡毛掸子容易引起“灰尘转移”，更好不要这样做。地毯很轻易吸收灰尘和水蛭虫，霉菌孢子等，再难以清洗，会使人产生一些不良反应，如皮肤发痒、打喷嚏等，尽量不要使用地毯。

　　Secondly, we should give full play to the function of the range hood. Whether it's cooking or boiling water, as long as you open the kitchen utensils, you should open them with a lampblack machine, close the kitchen door and open the windows at the same time, which is conducive to air flow and eliminate pollutants. When flushing the toilet, put down the toilet cover and try not to open it when not in use. It is best to use solid slow-release disinfectant in water tank, select safe and effective air disinfection products, and purify air. In addition, when cleaning, it is best to use a vacuum cleaner, if possible, or use a mop and a wet rag. If use broom, action wants light, do not lift dust to aggravate air pollution. Feather duster is easy to cause "dust transfer". It is better not to do so. Carpet is very easy to absorb dust and leech insects, mold spores, etc., and then difficult to clean, will cause some adverse reactions, such as skin itching, sneezing, etc., try not to use carpet.

　　使用空调的家庭，更好能使用呼吸机。其中换热器效率更好,一些热交换效率可以达到70%左右,寒冷的空气排放可以有效地冷却热在从外部注入新鲜空气,可以使室内空气保持新鲜,可以大大节约能源,降低家庭电力成本,是一种两全其美的选择。另一个有效的方法是使用空气净化器。常用的净化器有以下几种:(1)静电式室内空气净化器(主要用于可吸入颗粒物的净化);(2)过滤室内空气净化器(主要用于可吸入颗粒物和气态污染物的净化);(3)复合室内空气净化器(主要用于可吸入颗粒物和气态污染物的净化);(4)净化涂料(如用于净化气态污染物的纳米涂料)。

　　For air-conditioned families, it is better to use a ventilator. Among them, the efficiency of heat exchanger is better, some heat exchange efficiency can reach about 70%, cold air emission can effectively cool the heat and inject fresh air from the outside, can keep the indoor air fresh, can greatly save energy, reduce the cost of household electricity, which is a kind of choice with both advantages. Another effective method is to use air purifier. The commonly used purifiers are as follows: (1) electrostatic indoor air purifier (mainly used for the purification of inhalable particles); (2) filtration indoor air purifier (mainly used for the purification of inhalable particles and gaseous pollutants); (3) composite indoor air purifier (mainly used for the purification of inhalable particles and gaseous pollutants); (4) Decontamination coatings (e.g. nano coatings used to decontaminate gaseous pollutants).

　　要保持卧室空气清新，更有效、更经济的方法就是经常通风换空气。开窗通风应选择适当的时间，一般上午10点或下午3点，开窗通风半小时，可使室内空气进行交换。当然，如果外面的空气污染很严重，暂时不要打开窗户。如果有时间、条件，更好经常去大自然的新鲜空气中呼吸新鲜空气。

　　To keep the air in the bedroom fresh, the most effective and economical way is to ventilate and change the air frequently. Appropriate time shall be selected for window ventilation. Generally, 10:00 a.m. or 3:00 p.m. for half an hour, the indoor air can be exchanged. Of course, if the air pollution outside is very serious, do not open the window for the time being. If you have time and conditions, it's best to go to nature's fresh air frequently to breathe fresh air.
