Best Air Purifier to Relief Congestion From Dusty Air

Choosing the best air purifier for bedrooms to help you breathe clean air is important; It not only affects your physical health, but you also get the mental benefits from getting a good night’s sleep.

Most people don’t realize how polluted the air is that they are breathing – especially when sleeping. Air pollution indoors can be a serious problem.

Having an air purifier in your bedroom can make the air cleaner, helping you make the most of your sleep time and reducing exposure to any allergens present in your bedroom.

Suppose you live in an area with high levels of airborne contaminants or heavy traffic near your home. In that case, this is especially important – but even if you live somewhere further from the urban life, poor bedroom indoor ventilation can lead to dust accumulation, leading to poor air quality.

Aside from removing dust particles in the air, air filters can reduce smoke particles, relieve seasonal allergies, or even for a pet owner dealing with pet fur.

What are the important features when buying an air purifier?

In the past, the only concern people had when buying an air purifier was how much it costs. All modern air purifiers have a variety of features. These features include a unique design, washable filters, or replaceable HEPA filters.

Since you are investing in your health, quality is more important than cost when purchasing air purifiers; here are some factors to consider when choosing the best air purifiers.

Air Volume Coverage

Your air purifier’s clean air delivery rate depends on the air volume coverage that your air purifier can. This is usually measured in square feet.

A good air purifier should suit the size of your room – Units with a clean air delivery rate below 200 square feet are suited for smaller rooms, while units above 300 square feet are suitable for bigger rooms.

Having an air purifier strong enough to circulate the air in a large room is important. Using small air purifiers will not effectively provide enough air purification in bigger bedrooms because it simply cannot move the air fast enough.

Fan noise

Another factor to consider is the fan noise from the unit. Units with a high air volume coverage will most likely also make more noise because they have stronger fans.

Most air purifiers have different fan speed control. Running it at the highest speed is not recommended because the noise level can get pretty high. Operating it at low speeds will reduce the fan’s noise level but lower the airflow rate and cleaning power.

Most people turn on the sleep mode while sleeping for quiet operation, but if you actually want the noise, the fan of air purifiers can also be used as a white noise machine while you sleep.

Replacement filters

Depending on your unit, the filters inside your air purifier will need to be replaced once every 6-12 months. Filter replacement is an ongoing operating cost, so it’s important that you choose a unit with affordable filters.

Many modern air purifiers have eco-friendly washable HEPA filters instead of disposable ones typically used in air purifiers and other appliances such as vacuum cleaners. This can save money in the long run.

Type of filter

Not all air purifiers are alike. The standard air purifier comes with a true HEPA filter, which can effectively remove fine particles in the air, even when they are smaller particles like pet dander.

Many HEPA air purifiers also come with charcoal filters or an activated carbon filter that helps remove fine dust particles while removing odor at the same time.

There are usually multiple layers of filters in an air purifier.

Now that you know the important features in choosing the best air purifier, we have reviewed the many purifiers in the market so you can enjoy the best air purification today.

Best Air Purifiers With Washable Filters

Since air purifiers reduce the number of air particles, the dust and air pollutants accumulate in the air purifiers filter. Once the HEPA filters are full, the filter’s efficiency to purify the air is reduced until a replacement is used. The operating costs for air purifiers can be reduced drastically by getting one that has washable filters. Note that most of these are washable pre-filters, and you still have to get a replacement for the main filter.

Where to place air purifiers in your room

The placement of air purifiers is important to ensure air pollutants are effectively being filtered out of your room. The best placement for air purifiers varies from individual homes.

Here are some tips on the best placement for your air purifier:

  • Avoid putting an air purifier in corners – this will cause airflow problems as dust can easily accumulate and block up filters more quickly than other areas because no fresh currents reach them from any direction.
  • Reduce clutter around an air purifier – furniture, clothes, or other objects can reduce airflow and make the appliance work harder than necessary to keep your home’s atmosphere clean and healthy.
  • Place near a window or door encourages airflow and better distribution of purified air around the room, reducing pollutant concentration in particular locations.
  • Place close to pollutant source – if you are trying to eliminate pet odors, for example, from a litter box, placing the air purifier close to the source ensures the purifier cleans the air quickly.

Final Thoughts

Air purifiers are great for reducing the amount of dust in your home and making it a healthier place.

Depending on what you need from your air purifier, various models are available for purchase that will suit different needs.

This article has provided some helpful tips about finding the right one for you and where to place them around your home so they can effectively filter out pollutants from the air.

With these considerations, now you’re armed with everything you need to keep those pesky allergens at bay without breaking the bank!


1. Do I need an air purifier?

An air purifier is optional but can help greatly improve the air quality in your bedroom. Breathing clean air while you will allow you deeper rest.

We highly recommend it, but you might not need one if you do not wake up with congestion.

2. Can I vacuum my air filter?

While it may look like it’s removing all the dust, vacuuming air filters only removes the outer layer of dust. The inner parts of the filters are still full of dirt. This is not recommended as vacuuming can damage the filter and reduce its efficiency.

Getting a brand new filter will ensure the appliance is running at the best efficiency.

3. What is the difference between air purifiers vs. humidifiers?

An air purifier is a device that takes in dirty, polluted air from the room and cleans it by trapping pollutants inside of filter media.

A humidifier increases humidity levels within a space, adding moisture to the air and helping reduce congestion.

4. Are expensive air purifiers worth it?

The most expensive air purifiers do not necessarily translate to the best air purifiers.

More expensive air purifiers have features that you may not need, such as the air particle counter, the ability to circulate large volumes of air, or even built-in pink noise machines.

The most important thing to consider is if you need the feature, as cheaper air purifiers can work as well as any other air purifiers.

Just remember to consider the ongoing operating costs when replacing the filter.
