6. Alen BreatheSmart Air Purifier

4.6 out of 5 stars (4.6 / 5)

alen-breathesmart-reviewPros

The Alen BreatheSmart is an interesting device, because it can be customized by choosing different purifiers to suit your intended use. This air purifier allows you to choose between four different HEPA-type purifiers.

It is important to remember that these HEPA-type purifiers are not as strong as true HEPA filters. HEPA-type purifier only clean up to 95% of the particles in the air. If you are buying an air purifier to alleviate allergy or asthma symptoms, then it is important to remember that a device with a HEPA-type filter will not be suitable.

The four filters available for the Alen BreatheSmart air purifier are:

  • A HEPA-Pure filter, which is a standard filter used to remove everyday allergens in the air.
  • A HEPA-Silver filter, which is used to remove germs and mold from the air.
  • A HEPA-FreshPlus, which is used to remove chemicals and smoke from the air.
  • A HEPA-OdorCell, which is used to remove unpleasant odors from the air.

Size of Device

The Alen BreatheSmart is not a huge device; it is well suited to be kept in one room. The style and design of the device is one of the most popular aspects for users. You are able to switch the colors and textures of the panels to allow it to blend with the decor of your room.

The Alen BreatheSmart is an incredibly powerful device that can be used in large rooms up to 1100 square feet in size. However, it is most suitable for rooms up to 280 square feet.

One issue with the Alen BreatheSmart is that it is loud regardless of which speed setting you use. This is unsurprising due to how powerful it is, but this does mean that it is unsuitable for bedrooms and rooms where you do not want distracting noises.

How Often Do You Need to Change Filters?

Regardless of which variation of the HEPA-type filter you choose, you should expect to replace it once every year. The good news is that the device also includes a pre-filter which should help you get the most life out of the HEPA-type filter you choose. The pre-filter is washable, meaning that you will not need to spend extra money replacing it.

Conclusion

The Alen BreatheSmart is perfect for people who really want to have the option to customize the device.

Ultimate Guide to Finding the Best Air Purifier

Thankfully, our page will help you find the best air purifier without needing to spend night and day trawling Amazon reviews! We’ll pick out the best of the bunch, but remember that not every option is the best for your particular needs.

Some Helpful Links:

What is an Air Purifier?

An air purifier is a device that is designed to improve the quality of indoor air. It does this by removing particles in the air along with harmful chemicals and allergens which can lead to health problems after long-term exposure.

How Do Air Purifiers Work?

Different air purifiers use different kinds of technology to filter particles from the air you breathe.

  • Pre-filters are used to capture larger visible particles like dust, lint, and hair.
  • Carbon filters remove harmful pollution from the air and reduce unpleasant odors.
  • True HEPA filters capture up to 99.97% of allergens as small as 0.3 microns.
  • HEPA-type filters use similar technology to trap all allergens but are not as effective as true HEPA filters.
  • UV radiation breaks down the molecular structure of germs, molds, viruses, and bacteria and destroys them.
  • Ionizers produce ions that latch on to harmful viruses and bacteria and make them fall to the ground, ensuring you do not breathe them in.

Many manufacturers will create air purifiers that use a variety of the different technologies listed above to ensure that you’re breathing clean air.

Should I Buy an Air Purifier?

Indoor air has been found to be up to five times more polluted than the air you find outdoors. This is one of the main reasons that an air purifier can be of benefit to absolutely anyone.

If you suffer from allergies or asthma, then you will find that air purifiers are even more useful, because your lowered exposure to polluted air will help decrease your allergy and asthma symptoms.

However, air purifiers are not a replacement for keeping your home clean by dusting, vacuuming and mopping regularly.

How to Determine the Efficiency of the Device

The CADR rating, assigned by the Association of Home Appliance Manufacturers, is the best way for us to do this.

The Clean Air Delivery Rate (CADR) allows you to understand how many cubic feet of air is filtered in one minute. This is worked out by the ability of a purifier to remove dust, smoke or pollen from the air. The rating works on an upward scale, so the more effective an air purifier, the higher the CADR rating.

How Much Area Does the Device Cover?

If you have a big family and you want to clean the air for all of them, then you want a device that is designed to do that specific job.

In these situations, you will not benefit from buying a device that is only designed for the use of one person.

  • Buy a device that covers a larger area than your room.
  • Choose a device that has a CADR rating of 1 per 1 square foot.

By choosing something more powerful, you can ensure that the device should be strong enough for your needs. It also means that you should be able to use it at a lower level rather than on high all the time – which is also a bonus because it should keep the noise down!

Are They All So Noisy?

If you will use your purifier while you are sleeping or working at home, then you might think these stronger models are not suitable for you.

As suggested previously, whether you choose a quieter model or not, the best thing to do is always look for a device that is more powerful than you need.

Avoiding Extra Expenses!

The biggest expenses throughout the life of an air purifier are replacement filters and energy consumption.

Commonly, filters need to be changed every three to twelve months, depending on how often you use your air purifier. The cost of filters may be quite high if you choose a high-end model purifier. The most expensive filters should be somewhere around $200, while the cheapest should be around $10.

Added Benefits With Extra Features!

Some purifiers come with timers, power indicators, and air quality sensors which can provide real benefits when used properly.

Look for the features that will really help you, but don’t allow added gimmicks to fool you into buying a low-quality air purifier.

Other Notable Units Include:

Are They Worth the Money?

Air purifiers are not cheap, especially when you take into account the cost of electricity and replacement filters. Whether making this investment is useful to you depends on a number of different things:

If you do suffer from allergies and asthma, then you should certainly consider investing in an air purifier from gases, because you will benefit.

Tell Me What the Best Air Purifier is!

Unfortunately, it is not possible to name one air purifier which stands head and shoulders above the competition. When you are deciding which one is best for you, bear the following in mind:

  • True-HEPA filters are useful for removing the tiny particles which cause order for people with asthma or allergies. A device featuring a True-HEPA filter may be the best air purifier for people who are struggling with these conditions.
  • Activated carbon filters remove harmful chemicals in the air and also eliminate bad smells. A device featuring an activated carbon filter may be the best air purifier if this is important to you.
  • A purifier with an ionizer or that features UV radiation will destroy airborne bacteria and viruses. This may be the best air purifier if you are often feeling sick.
  • A simple cleaner which doesn’t use cutting edge technology can still be of benefit for people who simply want to lower the amount of dust and pollen in your home.

Are There Safety Issues With Air Purifiers?

One slight concern with air purifiers is that some produce small amounts of ozone. Ozone is one of the main components found in smog or mold, and it can exasperate symptoms for people with respiratory problems. If you suffer from asthma or another similar condition, then this can be a concern for you. This problem for health is only found in devices using ionizer or plasma wave technology. If this is going to be a concern for you, then you should avoid these devices or ensure that you can turn off the ionizer function.

Conclusion

When it comes time to choose the best air purifier for your home and health, knowing how and where, and what brands (like oransi max) look can be difficult for many people. Now that you have more information on how air purifiers work, hopefully, you have a better understanding of what your specific needs are.
