空气净化器使用指南：改善空气质量的必备设备

空气净化器使用指南：改善空气质量的必备设备1. 引言1.1 概述空气净化器是一种用于改善室内空气质量的设备。

随着人们对空气污染越来越关注，空气净化器已经成为很多家庭和办公场所必备的设备之一。

本文将向读者介绍如何正确选择和使用空气净化器，以改善室内空气质量并提高健康水平。

1.2 文章结构本文分为五个主要部分：引言、空气质量问题、如何选择空气净化器、使用空气净化器注意事项以及结论。

在引言中，我们将简要介绍文章的内容和目的，并为读者提供整体框架。

1.3 目的本文旨在帮助读者了解空气污染对健康的影响，并为他们选择合适的空气净化器提供指导。

同时，我们还将强调正确使用和维护空气净化器的重要性，并分享一些有关未来发展趋势的预测。

以上是“1. 引言”部分的内容，接下来我们将深入探讨“2. 空气质量问题”。

2. Air Quality Issues2.1 Sources of Air PollutionAir pollution is caused by various sources, both indoor and outdoor. Common outdoor sources include industrial emissions, vehicle exhaust, and pollen from plants. Indoor sources mainly consist of tobacco smoke, cooking fumes, household cleaning products, and volatile organic compounds (VOCs) emitted by furniture and building materials. These pollutants can all contribute to poor indoor air quality.2.2 Pollutants that Affect HealthSeveral pollutants pose significant risks to human health. Particulate matter (PM) refers to tiny particles suspended in the air, such as dust, pollen, and soot. Fine PM with a diameter of less than 2.5 micrometers (PM2.5) can penetrate deep into the lungs and even enter the bloodstream, causing respiratory problems and cardiovascular diseases.Volatile organic compounds (VOCs), released from products like paints, adhesives, and cleaning agents, can cause eye irritation, headaches, allergic reactions, and long-term health effects after continuous exposure.Secondhand smoke contains harmful substances like nicotine, carbon monoxide (CO), and carcinogenic chemicals that increase the risk of respiratory infections, asthma attacks, lung cancer, and other diseases.Formaldehyde is another common indoor pollutant found in furniture glue and building materials. Prolonged exposure to formaldehyde may lead to respiratory issues and potentially increase the risk of developing cancer.Other pollutants include nitrogen dioxide (NO2) from gas stoves or heaters that can aggravate respiratory conditions such as asthma; ozone (O3), which at ground level can irritate the respiratory system; and carbon dioxide (CO2), mainly produced through human respiration but can accumulate in poorly ventilated spaces leading to drowsiness and reduced cognitive function.2.3 Role of Air PurifiersAir purifiers play a crucial role in improving air quality by effectively removing or reducing harmful pollutants. They utilize various technologies to capture and filter out particles and undesirable gases.High-efficiency particulate air (HEPA) filters are designed to trapmicroscopic particles, including PM2.5, pollen, dust mites, and pet dander. Activated carbon filters can remove VOCs, odors, and airborne chemicals by adsorbing them onto their porous surfaces.Some advanced air purifiers also incorporate additional features like ultraviolet (UV) light sterilization to kill bacteria and viruses, ionizers to neutralize charged particles, and sensors to monitor air quality indicators such as PM2.5 levels or volatile compounds.By using an air purifier in your indoor space, you can significantly reduce the concentration of pollutants in the air, providing cleaner and healthier breathing environment for you and your family.Note: While air purifiers can help improve indoor air quality and mitigate the impact of pollutants, they should not be considered as a sole solution for addressing more complex issues like mold growth or excessive humidity. Proper ventilation and addressing the root causes of pollution are also important aspects of maintaining good indoor air quality.3. 如何选择空气净化器3.1 适合房间大小和污染级别选择空气净化器时，首先要考虑的是房间的大小和污染级别。

2、过滤网，部分过滤网是需要定期拿到太阳底下去晒一晒，净化效率才能较好地保持，如活性炭滤网。

3、除臭滤网，少数品牌的空气净化器的除臭滤网，以达到可水洗的技术层面，可以通过水洗，即保持净化效率，延长换滤网的周期。

4、离子发生器，一般是内置的，不需要清洁，较好的离子发生器工作效率都较高。

PM2.5吸附了很多有害气体、重金属和致癌物，它能够在呼吸系统中直接产生毒害作用，引发各种呼吸系统疾病，还可以进入血液，诱发血栓的形成，甚至致癌。

因此为了让我们呼吸的空气中没有PM2.5，我们必须使用空气净化器。

以上就是空气净化器的使用方法以及空气净化器保养指南的内容。

空气净化器的使用方法

空气净化器的使用方法空气净化器是一种能够过滤空气中灰尘、细菌、病毒、花粉和异味等有害物质的电器产品。

它通过吸入室内空气，经过过滤和净化后释放净化后的空气，提供给人们一个清洁、健康的室内环境。

那么，如何正确使用空气净化器呢？首先，选择适合的空气净化器。

市场上有很多品牌和型号的空气净化器，消费者可以根据自己的需求和预算选择适合自己家庭的净化器。

一般来说，家庭空气净化器的空气净化能力应该与房间的面积相匹配，能够有效覆盖房间的空气污染物。

此外，净化器的噪音也是一个需要考虑的因素，尽量选择噪音小的产品。

在使用空气净化器之前，需要将房间的门窗关闭，确保室内空气流通时不会受到外界的污染。

同时，及时清理房间内的灰尘，保持环境整洁，减少空气中的污染源。

对于有过敏体质的人群，空气净化器的使用更加重要，可以帮助过滤室内空气中的过敏原，减少过敏反应的发生。

接下来，正确放置空气净化器。

将净化器放置在房间中心位置，不要与墙壁或其他大型家具太靠近，保持一定的空间让它吸纳空气。

净化器的进风口最好不要靠近门窗或者其他容易吸入污染物的地方。

同时，不要在空气净化器周围摆放物品，以免阻碍空气流动。

使用空气净化器时，要注意合理调节净化器的工作模式。

根据实际情况选择自动模式、舒适模式或者睡眠模式等不同功能。

自动模式下，净化器会根据室内空气质量自动调节风速和工作时间；舒适模式下，净化器会在低噪音的情况下进行工作，确保用户的舒适体验；睡眠模式下，净化器工作噪音更低，给用户一个静谧的睡眠环境。

此外，还可以根据需要调节净化器的定时功能，设定净化器工作的时间段。

定期保养和维护空气净化器也是很重要的。

经常更换空气净化器的滤芯，一般建议每3个月更换一次，如果家庭成员有特殊需求，如过敏体质，滤芯更换的频率可以更快一些。

及时清洗净化器的外壳，以保持净化器的整洁。

同时，定期检查和清洗净化器的其他部件，如进风口和出风口等。

如果空气净化器出现故障，需要及时维修或更换。

Portable Air Cleaners and Furnace or HVAC Filters in the HomeIndoor air contains pollutants that can affect human health. Some of these pollutants come from outdoors, and others come from indoor sources and activities, such as cooking, cleaning, secondhand smoke, building materials, consumer products, and home furnishings. These indoor air pollutants can be particles or gases, including volatile organic compounds (VOCs). Common contaminants that can be found indoors include particulate matter (including PM 2.5 [fine] and PM 10 [coarse]), formaldehyde, mold, and pollen. Indoor air quality will vary from home to home and over the course of a day within a home. Since most people spend about 90% of their time indoors, mostly in their homes, much of their exposures to airborne pollutants will happen in the home.The most effective ways to improve your indoor air are to reduce or remove the sources of pollutants and to ventilate with clean outdoor air. In addition, research shows that filtration can be an effective supplement to source control and ventilation. Using a portable air cleaner and/or upgrading the air filter in your furnace or central heating, ventilation, and air-conditioning (HVAC) system can help to improve indoor air quality. Portable air cleaners, also known as air purifiers or air sanitizers, are designed to filter the air in a single room or area. Central furnace or HVAC filters are designed to filter air throughout a home. Portable air cleaners and HVAC filters can reduce indoor air pollution; however, they cannot remove all pollutants from the air.Tips For Selecting a Portable Air Cleaner, Furnace Filter, or HVAC Filter When selecting a portable air cleaner, furnace filter, or HVAC filter, keep in mind:No air cleaner or filter will eliminate all of the air pollutants in your home.Note that most filters are designed to filter either particles or gases. So in order to filter both particles and gases, many air cleaners contain two filters, one for particles and another for gases (in some cases including gases that have odors). Other air cleaners only have one filter, usually for particles. In addition, some air cleaners or filters are targeted to specific types of gases or VOCs. Consult the specific product packaging or labeling for more information.All filters need regular replacement.If a filter is dirty and overloaded, it won’t work well.PORTABLE AIR CLEANERSTo filter particles, choose a portable air cleaner that has a clean air delivery rate (CADR) that is large enough for the size of the room or area in which you will use it. The higher the CADR, the more particles the air cleaner can filter and the larger the area it can serve. Most air cleaner packaging will tell you the largest size area or room it should be used in.Portable air cleaners often achieve a high CADR by using a high-efficiency particulate air (HEPA) filter.To filter gases, choose a portable air cleaner with an activated carbon filter or otherfilter designed to remove gases. Note that there are no widely used performance rating systems forportable air cleaners or filters designed to removegases. The CADR rating system is for particles only.Activated carbon filters can be effective, providedthat there is a large amount of material used in thefilter.A portable air cleaner with a high CADR and anactivated carbon filter can filter both particlesand gases.Generally speaking, higher fan speeds and longerrun times will increase the amount of air filtered.An air cleaner will filter less air if it is set at a lowerspeed. More air will pass through the filter at higherfan speeds, so typically filtration will be greater at Portable Air Cleanerhigher fan speeds. Increasing the amount of time anair cleaner runs will also increase air filtration.FURNACE AND HVAC SYSTEM FILTERSFurnace and HVAC filters work to filter the air only when the system is operating. In most cases, HVAC systems run only when heating or cooling is needed (usually less than 25% of the time during heating and cooling seasons). In order to get more filtration, the system would have to run for longer periods. This may not be desirable orpractical in many cases since longer run times increase electricity costs and may also result in less reliable humidity control during the cooling season.Furnace and HVAC filters for homes are usuallydesigned to filter particles. If you decide to upgrade oruse a higher efficiency filter, choose a filter with at leasta Minimum Efficiency Reporting Value (MERV) 13rating, or as high a rating as your system fan and filterslot can accommodate. You may need to consult aprofessional HVAC technician to determine the highestefficiency filter that will work best for your system.Other devices that do not have filters may alsoremove particles and gases. They usually fit insidethe HVAC ductwork and are more common in largeand commercial buildings. See the EPA technicaldocument, Residential Air Cleaners, 3rd edition, formore information: /indoor-air-quality-iaq/residential-air-cleaners-second-edition-summary-available-information .EPA does not certify or recommend specific brands or models ofair filters or portable air cleaners.Q&A: Air Cleaning and FiltrationDo portable air cleaners and furnace/HVAC filters used in homes have the potential to improve my indoor air quality?Yes. Most portable air cleaners and furnace/HVAC filters can filter particles from the air. Some can filter the small particles of greatest health concern (PM 2.5). There are also air cleaners and filters that can filter both particles and gases. The longer the air cleaner runs, the more air it filters. Note that it is always important to reduce or remove the sources of indoor air pollutants and to ventilate with clean outdoor air. Filtration does not replace the need to control pollutants and ventilate.Can portable air cleaners and furnace/HVAC filters potentially have a positive impact on health?Possibly. Several studies using portable HEPA air cleaners have demonstrated small improvements incardiovascular and respiratory health. The improvements are typically small and not always noticeable to the individual, although they may be measureable by health professionals.For more information on particles and health, see:• EPA Indoor Particulate Matter: /indoor-air-quality-iaq/indoor-particulate-matter• EPA Particle Pollution and Your Health: /airnow/particle/pm-color.pdfCan portable air cleaners and furnace/HVAC filters reduce allergy or asthma symptoms?Possibly. Multiple studies with portable HEPA air cleaners have found improvements in one or more allergy and/or asthma symptom(s). The studies do not always show major improvements, and they do not show improvements in all symptoms.Can portable air cleaners and furnace/HVAC filters solve mold problems?No. Portable air cleaners and furnace/HVAC filters do not address the cause of mold and musty odors. Mold is caused by a water or moisture problem in the building that allows the mold to grow. To solve a mold problem, get rid of the source of the moisture and clean up the mold. Portable air cleaners and furnace/HVAC filters may remove some of the particles generated by mold. In some cases, they may also help reduce odors, but they will not resolve a mold and moisture problem.Note: Avoid portable air cleaners and furnace/HVAC filters that intentionally produce ozone. Ozone is a lung irritant. Note that in some cases, air cleaners that contain electrostatic precipitators, ionizers, UV lights without adequate lamp coatings, and plasma air cleaners may have the potential to emit ozone. Both the California Air Resources Board and the Association of Home Appliance Manufacturers maintain lists of air cleaners that have been tested and shown to emit little or no ozone.Q&A: Portable Air CleanersMost portable air cleaners have a CADR rating. What does that mean?Most portable air cleaners are rated according to their clean air delivery rate (CADR). This number is intended to help consumers select an air cleaner based on the size of the area it will be placed in. The higher the CADR, the more particles the air cleaner will remove and the larger the area it can serve. The rating is typically measured at the air cleaner’s highest speed.How do I choose a portable air cleaner that will remove the small particles of greatest health concern (PM 2.5) effectively?Some air cleaner packaging will indicate CADRs for removing three specific types of pollutants: tobacco smoke, dust, and pollen. These pollutants are used as examples to represent small-, medium-, and large-sized particles, respectively. To remove small particles, choose a portable air cleaner that has a high CADR for tobacco smoke, which represents the smallest particles. The CADR should be large enough for the size of the room or area you will use it in.How do I calculate the size of the room or area in order to pick the right air cleaner?Multiply the length and width of the area in which you intend to operate the air cleaner. The result will provide you with the size of the room or area in square feet. Compare this to the maximum recommended room size on the product packaging. If you have an open floor plan, you should consider the entire space that the air cleaner would serve. If you have high ceilings (above 8 feet), you should consider using an air cleaner that is sized for a larger area. If you have an area that is larger than any available product will serve, you could consider using multiple air cleaners.How do I choose a portable air cleaner that can remove volatile organic compounds (VOCs)?Choose a portable air cleaner with an activated carbon filter or other absorbent filter designed to removegases. They can be effective when there is a large amount of material used in the filter (the thicker the better). Research has not yet shown that other technologies such as plasma, photocatalytic oxidation, or ultraviolet (UV) light can remove gases effectively in portable residential air cleaners.Do portable air cleaners have noise ratings?Noise ratings are reported for some portable air cleaners. The ratingmay be shown on the product packaging. Noise levels depend in parton the fan speed setting. If noise might prevent you from running theunit, you might consider an air cleaner that has a low published noiserating. For reference, a noise rating around 50 decibels (dB) is roughly the operating noise of a modern refrigerator.Where should I put a portable air cleaner?Consider placing the unit in the room(s) you spend the most time in.Many units are designed to be placed on the floor, although someare designed for tabletops. Either way, make sure the airflow is notobstructed. Keep air cleaners away from curtains and anything thatmight block airflow. If the air cleaner causes an uncomfortable draft,then redirect the airflow away from you.What does it mean if a portable air cleaner has the EPA’s ENERGY STAR ® label?Some portable air cleaners sold in the consumer market are ENERGY STAR qualified. The ENERGY STAR label means that it meets strict energy efficiency guidelines set by EPA. The label does not refer to its air-cleaning effectiveness in any way.Q&A: Heating, Ventilation, and Air-Conditioning (HVAC) System Filters and Furnace FiltersHow are HVAC/furnace filters rated?There are several commonly used filter rating methods. These include the Minimum Efficiency Reporting Value (MERV), Filter Performance Rating (FPR), Microparticle Performance Rating (MPR), and others. MERV is based on a national consensus standard. The FPR and MPR rating methods are proprietary. For all rating methods, the higher the filter rating, the higher the removal efficiency for most particle sizes.How do I choose an HVAC/furnace filter that will be most effective at removing small particles of greatest health concern (PM 2.5)?Use the highest-rated filter that your system fan and filter slot can accommodate. Filters with a MERV of 13 and above are required to demonstrate at least 50% removal efficiency for the smallest particles tested.This is an example of a label from a portable air cleaner. Used with permission from the Associa-tion of Homes Appliance Manufacturers (AHAM).How do I know if my system can accommodate a MERV 13 filter or higher?Most furnaces and HVAC systems can accommodate a MERV 13 filter without creating equipment problems, provided that the filter is replaced frequently. Sometimes it can be difficult to tell whether a system can use a higher efficiency filter since HVAC systems are not commonly labeled with any filter recommendations. To be certain a filter will work with your system, consult a professional HVAC technician. The technician can determine the most efficient filter that your system can use. An HVAC technician can also modify the system to use a higher efficiency filter. How can I tell if the filter is the right size for my furnace/HVAC system?Filters commonly come in thicknesses of 1 to 5 inches, with a variety of lengths and widths to match common sizes of filter frames in furnaces and HVAC systems. Make sure the filter fits snugly so air does not leak around the filter and you do not have to bend or crush the filter to make it fit.How often do I need to change my filter?Replace filters according to manufacturer’s recommendations. Many factors can affect how quickly filters get dirty. Manufacturers typically recommend replacement every 60 to 90 days. If you notice that filters appear heavily soiled when you replace them, you should consider changing them more frequently.What if I have a window air conditioner or a wall-mounted “ductless” air conditioner?Most window air conditioners and wall-mounted units are intended for temperature control rather than air filtration. These units typically have limited filtration intended to keep the inside of the air conditioner clean rather than remove fine particles from the indoor air.For more information:EPA Indoor Air Quality website/indoor-air-quality-iaqEPA Technical Guide to Residential Air Cleaners/indoor-air-quality-iaq/residential-air-cleaners-second-edition-summary-available-information Important notesOzone generators that are sold as air cleaners intentionally produce the gas ozone.
