干净的空气对每个人都是必不可少的，尤其是对COPD的人。过敏原等过敏原和空气中的污染物会刺激您的肺部，并导致更多的症状耀斑。
您家或办公室中的空气似乎足够干净。但是您看不到的可能会伤害您。
烟雾，ra和其他化学物质等污染物的微小颗粒可以通过敞开的门和窗户以及通风系统进入您的房屋。
还有一些来自清洁产品的室内污染物，用于建造房屋的材料，灰尘和霉菌等过敏原以及家用电器。
这些来源的结合是为什么室内污染物的浓度是高两到五倍据环境保护署称，比室外污染物的污染物。
清除房屋空气的一种方法是使用空气净化器。这种独立的装置可以消毒空气并去除污染物和过敏原等细颗粒。
Purifiers filter the air in one room. They’re different from the air filter that’s built into your HVAC system, which filters your whole house. Air purifiers can cost hundreds of dollars.
An air purifier can help clear your home’s air of allergens and pollutants. Whether it will help improve COPD symptoms is still uncertain. There hasn’t been much research. The results of the studies that do exist have been inconsistent.
Yet the research does suggest that reducing particles and allergens in the air may ease lung symptoms.
例如，
有几种类型的空气净化器。有些工作比其他更好。一些实际上可能对您的健康有害。这是一个快速分解：
- HEPA filters.This is the gold-standard filter for removing airborne particles. It uses mechanical ventilation — fans that push air through pleated fibers like foam or fiberglass — to trap particles from the air.
- 活性炭。This model uses an active carbon filter to trap odors and gases from the air. Although it can catch larger particles, it typically misses smaller ones. Some purifiers combine a HEPA filter with an activated carbon filter to trap both odors and pollutants.
- 紫外线（UV）光。UV light has the ability to kill germs like viruses, bacteria, and fungi in the air. For a UV air purifier to kill these germs, the light must be strong and stay on for at least several minutes or hours at a time. This isn’t the case with all models.
- 电离子。通常，空气中的颗粒具有中性电荷。电离器对这些颗粒充电，这使它们粘在机器或其他表面上的板上，因此您可以将其清洗。
- 静电空气净化器和臭氧发电机。These purifiers use ozone to change the charge of particles in the air so they stick to surfaces. Ozone can irritate the lungs, making it a bad choice for people with COPD.
良好的空气净化器的关键是，它会过滤颗粒10微米或直径较小（人头发约为90微米）。
您的鼻子和上呼吸道非常擅长滤出大于10微米的颗粒，但是小于该颗粒很容易进入您的肺和血液。
包含HEPA过滤器的空气净化器是金标准。选择一个包含真正的HEPA滤波器，而不是HEPA型滤波器。尽管它更昂贵，但它会从空中清除更多的颗粒。
Avoid any purifier that uses ozone or ions. These products could be harmful to your lungs.
使用空气净化器可能有助于清洁房屋中的空气，因此您可以呼吸少的颗粒，从而刺激肺部。
Cleaner indoor air might help your heart, too.
暴露于空气中的颗粒会导致炎症损害血管。在
When choosing an air filter, you have a few different options.
HEPA代表高效颗粒空气。这些过滤器在清除空气方面非常有效，因为它们去除
对于进入过滤器的每10,000个粒子，只有三个粒子将通过。
选择HEPA过滤器时，请查看其最低效率报告值（MERV）。该数字从1到16，显示了过滤器在捕获某些类型的颗粒时的有效性。数字越高，越好。
Some air filters are disposable. You change them every 1 to 3 months and throw out the old one. Others are washable. You check them once a month, and if they’re dirty, you wash them.
Disposable air filters offer more convenience, but you’ll spend more to keep replacing them. Washable air filters save you money, but you’ll need to keep up with the cleaning.
在addition, filters are made from several different materials:
- Pleatedfilters are designed to last longer with less maintenance.
- 聚酯纤维filters trap lint, dust, and dirt.
- Activated carbonfilters help control odors in your home.
- 玻璃纤维过滤器由夹心污垢的旋转玻璃制成。
You need to keep the filter in your air purifier clean so it can work effectively. Plan to clean your purifier about once a month.
你应该唯一的过滤器d never wash are HEPA or carbon filters. Change these filters every 6 months to 1 year.
To clean your filter:
- Turn off and unplug the air purifier.
- 用湿布清洁外面。使用软刷清除顶部通风口的任何灰尘。
- Remove the front grill and prefilter and wash them with warm, soapy water. Dry them with a towel before putting them back inside the machine.
- Use a dry, soft cloth to wipe down the inside of the air purifier.
An air purifier can remove some pollutants and allergens from the air in your home. While these machines haven’t been proven to help with COPD, they may improve asthma symptoms.
为了获得最佳效果，请选择带有HEPA过滤器的净化器。确保通过定期洗或更换过滤器来保持空气净化器清洁。
