How to Choose a Portable Air Purifier

So what are the things you should keep in mind to find your perfect air purifier? It surely can be a confusing thing to buy. An air purifier is a personal purchase, however, there are some factors you need to look for in a decent air purifier.

Air Cleaning Technology

There are a ton of filters that air purifiers come with, and not all are useful for you. According to the needs of your area, you should decide which filter to look for. For example, a HEPA filter is generally good for cleaning super small particles and is necessary to have in your filter. Furthermore, if one smokes, then it is important to invest in an air purifier that has a carbon filter to get rid of the smoke and odor left behind from smoking.

Size and Portability

Industrial-sized air purifying units are hard to store, hard to clean, and hard to move. Therefore, it is ideal to invest in an air purifier which is portable if you need to move it from room to room. The larger the purifier, the harder it is to blend in with your surroundings. Particularly, if you are living in a small space, it is better to invest in a portable air purifier.

Noise Reduction

It's important to choose an air purifier which produces minimal noise. Units with high fan speeds tend to produce more noise.

It can be quite upsetting for people, especially the elderly if you are placing the air purifier in their room. Thus, this is another aspect to consider before buying one.It can also disturb sleep or bother children and pets if your unit makes too much noise.

  • Fabric, particle, and carbon filters

CONS

  • Sleep mode emits constant blue light
  • Highest setting produces a slight noise

What Recent Buyers Report

Most customers loved the design, stating that the purifier works well in small rooms. They enjoyed the auto mode indicator, although one buyer mentioned annoyance at the blue sleep mode light at night. The unit is also silent, except at the highest setting.

Why it Stands Out to Us

This purifier has a lightweight design that’s not too bulky. There’s an outer fabric filter that you can remove and wash at any time. Underneath this layer, you’ll find a particle remover and an activated carbon filter for odors and VOCs.

The CADR for smoke, pollen, and dust are 123, 96, and 107, respectively. There are five air changes per hour (ACPH) if you leave the purifier on auto mode. The light indicator at the top will let you know when you need to change any filter, while also which setting is active.

Editor’s Pick:

Alen Pure BreatheSmart 45i, Dust, Mold, Odor, White

PROS

  • Pink soothing noise for improved sleeping
  • Five different light indicators for air quality
  • B4-Pure filter to remove allergy and asthma triggers

CONS

  • Unpleasant hum at highest speed

What Recent Buyers Report

Many buyers were pleased with the smooth operation and how well it purified the air. They mentioned that it worked well in several rooms while aiding with their allergies. Of the available features, the light indicator and sensor were their favorites.

Why it Stands Out to Us

We love the slim design of this air purifier when compared to its other dimensions. Not only does it have a B4-Pure filter for reducing allergies that affect asthmatics, but it also has 45i layers for combatting germs, mold, bacteria, and fungi. There’s a soothing pink noise for the evening so that you can sleep peacefully.

Instead of the standard three colors for indicating the current air quality, you’ll have five at your disposal. It auto-adjusts based on the particle volume in the vicinity. If you’d enjoyed a night light, you can set it to full brightness or dim it to an acceptable level.

Bottom Line

The Alen BreatheSmart 45i is an excellent choice if you have allergies, especially ones that affect your lungs. Its slimline design makes it suitable for tight spaces, and you’ll have a restful night with the pink noise. Of course, it outshines many competitor brands for air purity performance.

Best Places to Use an Air Purifier

You must be thinking why does it matter? Well, the location where you place your air purifier matters a lot. The good thing about having a portable one is that you can use it in multiple locations. You can take it from room to room as you like.

In the Kitchen or Bathroom

Generally, the best place to use an air purifier would be the one which generates the most odors. Kitchen and bathroom are the two rooms of the house which are the source of most odors. Therefore, it is good to have an air purifier with a UV and HEPA filter. Both of these filters combined will get rid of odors and microbes that these two places of your house host.

In the Smoking Lounge

This is pretty self-explanatory. The smoke lounge or whichever part of your house you smoke in would be an ideal placement for your air purifier. It is going to get rid of all the smoke and the odors as well.

Do Not Put Near Electronic Devices

This is suggested as some electronics work on similar frequencies as your air purifier and therefore, they could be a hindrance to its functionality. Thus, it would be ideal for you to place it away from your television, computers, stereo equipment, etc.

In the Pet Area

Your pets shed dander and they produce unpleasant odors. Therefore, it would be ideal for you to place an air purifier wherever your pet normally resides or sleeps within the house.

How Do Portable House Air Purifiers Work?

Air purifiers draw in the pollutants and allergens from the surrounding space, using their filters to capture and eliminate them. There are various filters for various functions. For instance, one may remove dust and VOCs while another will reduce foul odors.

Portable house air purifiers have the additional feature of easy relocation from one room to another. Most units have sensors that detect how many harmful particles are in the area and a light indicator changing colors depending on the conditions. You’ll also have night mode settings for a peaceful night’s sleep.

Pros and Cons of Portable Air Purifiers 

Owning a portable air purifier comes with several advantages and disadvantages. Let’s look at a few of them. 

Health Benefits

One of the top benefits is to your health. With the built-in filters, the purifier eliminates air pollutants that negatively affect your lungs. If you’re an asthmatic or suffer from bronchitis, these germs and particles can be detrimental to your well-being. Not only will you feel better, but your sleep will improve.

Breath of Fresh Air

Besides removing allergens, air purifiers contain filters that eliminate foul odors. These scents include tobacco and marijuana smoke, pets, and exterior pollution. These units keep the interior smelling fresh for your visitors, even if they leave some bad scents themselves.

Easy Relocation

Whether you need to move the portable air purifier between rooms in the same house or take it with you to your cabin in the woods, these units are built for easy transport. Simply uninstall it, carry it to your vehicle, and you’re good to go.

Location Specific

The one downside is that the unit only caters to the area where it’s located. For instance, if you have it installed in your kitchen, don’t expect it to purify your bedroom’s air. 

How Do Portable Air Purifiers Compare?

You may be wondering how portable air purifiers compare to other units. Well, we’ve looked at some of them, as you’ll see in this section of our guide.

Whole House Air Purifier vs Portable

The most obvious benefit of a whole house air purifier is that it covers every room in your home, whereas the portable unit only caters to a specific area. 

Of course, the converse is true, whereby you can take your portable purifier with you to a different property. The larger device is also more expensive since it requires sensors and intakes in every space.

The installation cost isn’t the only factor, as you need to look at maintenance. The portable air purifier costs more to maintain due to changing filters more regularly.

However, you’ll have to pay for professional installation for the entire house unit.

Portable Air Purifier vs Ionizer

The main difference between these devices is the methods used to purify the air. With purifiers, filters trap odors and particles as the air passes through them. You’ll need to change the filters regularly, depending on how often the machine needs to clean the air in your home.

Ionizers, on the other hand, emit negatively charged ions into the surrounding air. These connect with positive ions in pollutants, which causes them to stick together. However, there’s the danger of introducing ozone into the air, known for irritating the lungs.

Portable Air Cleaner vs Purifier

Air cleaners are similar to purifiers but with limited functionality. For example, cleaners merely use filters for clearing dust and animal dander. Purifiers go the extra mile, taking care of those nasty germs, odors, VOCs, and allergens. Cleaners are known for their expensive filters, noisy fans, and high purchase costs. 

How to Maintain a Portable Air Purifier

Maintaining your portable air purifier depends on your model and the filters it includes. However, there are a few points to keep in mind. Here’s a quick overview:

  1. You can generally wash a fabric layer or any other pre-filter at home. Take extra care to do this regularly, depending on how often it cleans the air.

  2. When it comes to specialized layers, such as the HEPA filter, you’ll need to replace it with a new one. You can’t wash these, and you’ll need to find an exact match.

  3. Some purifiers have indicators that let you know when a filter needs cleaning or replacing. Others determine the replacement date based on how long it’s been operating. If you have the latter, first check to verify the filter’s state before buying a new one.

  4. A few units don’t have a system to detect if a filter is clogged or the ionizer is faulty. If you notice a strange smell from the purifier, it’s best to have a look and see where the issue lies.

Conclusion

In general, purifiers do an excellent job of cleansing the air of dust, allergens, germs, and odors. Portable units add the ability to move the device around your home or take it with you to your country club. You may need to maintain it more often, but it’s a lot cheaper than installing technology throughout your house.

With a portable air purifier, you can get clean air almost anywhere. Any one of these eight devices will be a great addition to your home, given the fact that these are some of the best out there. There is no doubt in the fact that air purifiers can be a hard choice given how many options there are in the market.

But you will always make the right decision if you know what you want out of the product. Therefore, the best advice would be to figure out your needs first and then invest in a unit.

People Also Ask

If we’ve left you with some lingering questions, here are a few FAQs from our readers that may help.

How Loud is a Portable Room Air Purifier?

It depends on the model you buy. For instance, extremely quiet or whispering units are between 15 to 20 dB(A). A good purifier will sound at about 32 dB(A), while a standard one emits 36 dB(A).

How to Reduce Sound of a Portable Air Purifier

If your device is louder than usual, it may be that the filter needs to be changed. Alternatively, you might be able to add some soundproofing to reduce the noise. You can also look for alternative filters that produce less sound.

How Much Do Portable Air Purifiers Cost?

How Long Should a Person Keep the Portable Air Purifiers On?

Some people leave air purifiers on throughout the night for a peaceful night’s sleep. Of course, the more you let it run, the higher your utility costs will be. Furthermore, you need to consider that keeping it off for prolonged periods means it needs to work harder to clean the air.

Can I Use a Furnace Filter In a Portable Air Purifier?

Furnace or similar HVAC systems have a design to accommodate MERV 13 filters between one and five inches thick. You’ll need to see if your portable air purifier can accommodate these layers, as most of them are designed for HEPA or activated carbon filters.

Will a Portable Air Purifier Protect Against Viruses?

Some devices can capture viruses or have unique UV lights to deal with them. You should check the specifications to ensure that the purifier you want to buy has this capability.
