It’s also packed with unique features, made all the more remarkable by its agreeable affordability. HoMedics is a brand that’s practically synonymous with quality and perfection, particularly in this niche. And judging by the positive reviews that this product has been receiving, it’s fair to say that they’ve scored another winner.

This ionic air purifier works best in small spaces, or ideally, a few feet away from where you’re sitting. This arrangement suits its dual-action carbon pre-filter down to a tee, ensuring that your space is entirely free from odors by collecting the larger particles and neutralizing them. In addition to this, it offers an essential oil pad that automatically distributes relaxing fragrances around your space and lets you control precisely how you want your room to smell.

It’s also equipped with a HEPA-Type filter that captures up to 99% of airborne contaminants with a size of 2 microns. While this filter is not as comprehensive as a true HEPA filter, it still performs creditably, especially in not-so-large spaces.

Interestingly, this ionic air purifier also offers excellent customizable features.

Also, it features indicators that let you know when the internal filters are due to be replaced.

InvisiClean Aura II Air Purifier

Buy From Amazon

The InvisiClean Aura II was built on the back of the success of the first model, and if you were expecting improved quality and performance, that’s what you’ll get from this ozone generator. It’s been built with the safety and protection of the entire family in mind, and when it comes to performance, this air ionizer scores top marks. It provides several features that are as impressive as they are remarkable for its price range. 

It weighs about 9 lbs, so it’s not the lightest. However, it sports a very compact design, with its small footprint ensuring that it can be moved and placed anywhere in the home. 

This air purifier’s four-tier cleaning model does a pretty good job of protecting you from harmful germs, allergens, and bacteria. Its carbon filter traps larger particles while also doubling as an odor neutralizer. Unlike other units that only feature HEPA-type filters, the InvisiClean Aura II boasts a True HEPA filter that effectively captures up to 99.9% of particles. It’s also equipped with UV light and an optional ionizer for more excellent protection against contaminants. 

It offers four-speed-speed settings, giving you the freedom to adjust air pressure to suit your needs. When you run it on the lower settings, it operates almost entirely noiselessly. On the other hand, if you crank up the dials to the highest, the fans get pretty loud, which is something you’d need to think about if night sounds are uncomfortable for you. 

Just as you’d expect, this ozone generator comes equipped with other practical features such as an automatic timer shutoff and sleep mode if all the flashing lights start to grate. Yet, for a gadget that offers all these bells and whistles, the InvisiClean Aura II is remarkably energy efficient. For the price which it’s offered at, this negative ionizer device is a steal. 


  • Energy efficient
  • Budget-friendly-friendly
  • Easy to use
  • True HEPA filter
  • Four-speed settings


  • Fan noise can get loud at turbo speed
  • High EMF radiation

Clarifion Negative Ionizer Generator

Buy From Amazon

Clarifion Negative Ion Generator does its job a little differently from how our top two air purifiers perform theirs, yet it delivers no less efficiently. For the sake of clarity, it’s more of an ion generator than an air cleaner since it lacks a carbon filter and a HEPA filter. Yet, it is adept at combating allergens and other contaminants and making rooms easier to breathe in. 

This negative ion generator is notably simple in both design and operation as an odor-free ozone generator. Weighing a little less than two pounds, it can fit snugly in your palms, your pockets, and wall sockets anywhere in your home. The flip side of this remarkable compactness is that you’ll probably need multiple units to cover a standard size room as it works best in small spaces. 

It sports a pretty sleek design that gives it a look of simple sophistication. The standout feature of the Clarifion Negative Ion Generator, apart from its LED indicator, is the ease with which it can be set up and operated. All you need to do is connect it to your wall sockets, and the Clarifion is ready to go. The LED light tells you when the device is connected correctly, but it may irritate your eyes after a while, especially at night. You may want to plug it a little far away from your bed, in this case. 

In terms of performance, Clarifion functions as you’d expect it. It releases about 10 million negative ions for every cm3, effectively eliminates a wide range of allergens, bacteria, pollutants, and pet dander. However, it does produce a significant amount of ozone, which may make this particular gadget unsuitable for use by people with a weak immune system. 

The Clarifion is very energy efficient, which, coupled with its near soundless operation, are attributes that contribute to its appeal. This product ticks all the right boxes for a price that’s more than right. 

HAPHID Negative Ion Generator/Plug-In Air Purifier

Buy From Amazon

Suppose quiet efficiency, simplicity, and affordability are qualities that you look for most in negative ion generators. In that case, you’ll find the perfect combination of them in the HAPHID Negative Ion Generator. This negative ion generator scores top marks for its effectiveness, while its uncomplicated outlook has endeared it to scores of enthusiastic customers. A general consensus is that it offers excellent value for money. airflow

It sports a straightforward but elegant design, and combined with its compactness, is one of the most portable and versatile air purifiers on the market. It also has no use for complicated set-ups, plug it into a wall socket as soon as you unbox it, and it’s ready to go. It’s also practically noiseless, which would have made it tricky to tell whether the air purifier is working or not. However, the led indicators on the body of this gadget provide feedback on this. 

This negative ion generator produces up to 32 million negative ions per second, making it pretty effective at getting rid of odors, pollutants, allergens, and a wide range of other contaminants. The negative ions attach themselves to airborne particles in your room and weigh them down to the ground. It may take a while for the effects of this device to become noticeable, but you can be sure of the results when you use this negative ion generator. 

You’ll save money in the short and long run if you opt for this product. Like other negative ion generators, you won’t have to purchase separate air purifier filters, or worry about changing them, when you buy the HAPHID Negative Ion Generator. In addition, it has low power consumption, and it’s offered at a very budget-friendly price. All things considered, this negative ion generator is a great backup option for your home. 

Holmes Desktop HEPA-Type Air Purifier

Buy From Amazon

Although the Holmes Desktop Air Purifier comes in a small package (it weighs just about 6 pounds), it does big things. One thing about this air purifier that instantly catches the attention is its price tag, which is almost unbelievably low. Unfortunately, this means that there’ll be a trade-off somewhere, and it’s true in this case. The design of this air purifier is relatively basic, and the plastic material needs to be handled with care. 

Nevertheless, this unit is very compact and versatile, comfortable anywhere in the room it finds itself. Its dual positioning design means that you can place it vertically or horizontally. However, when placed vertically, it doesn’t balance out well enough and may topple over, which may be too much for the material to take. 

This unit is equipped with a HEPA-type filter adept at eliminating small particles such as dust, pollen, pet dander, and other allergens. Its carbon filter also removes odors from smoke, stale air, and other household smells quite well. The Holmes Desktop Air Purifier offers an optional ionizer that makes it easier for the unit to capture particles and remove odors from the air. The ionizer produces ozone, though, which is harmful to the human body. It may be best to use the ionizer sparingly or not at all. 

This air purifier also offers flexible control with three-speed settings. Noise emission is low at the lowest speed, although it increases the higher you crank up the pressure. The CADR rating is not very impressive, meaning it’ll take longer for this unit to cover a standard room. This makes this air purifier most ideal for small spaces. 

All things considered, Holmes Desktop Air Purifier is a simple, no-frills unit that does what it’s supposed to do quite well, for a very reasonable price. 

Homedics TotalClean Tower Air Purifier

Buy From Amazon

HoMedics, once again, deliver their trademark excellence with this air purifier. It’s equipped with the company’s flagship 5-in-1 filtration system, along with other fabulous features. Everything from its 360-degree protection features to its intuitive touch controls has been intentionally designed to offer ample protection against contaminants of all kinds and ensure that you breathe and sleep easier. 

This is the smallest of all the models in the TotalClean series, although it still weighs a considerable 8.34 pounds, which makes it ideal for small rooms and office spaces of about 170 sq. ft. 

Its biggest attraction is unmistakably its 5-in-1 filtration system, which is pretty effective at killing bacteria and other germs, capturing contaminants and allergens, and dispelling unwanted odors. It boasts a pre-filter, 360° HEPA-type filter, 360° Carbon filter, UV-C light, and ionizer removing positive ions from the air. In addition to ridding your air of contaminants and bad smells, this air purifier can give your room a delightful scent with its aroma slot and pads. The air filter is built to last for about 12 months, so you won’t have to worry about getting a replacement until this period elapses. 

You can tweak this unit manually to suit your specific needs and preferences. It offers three fan speeds for customizable air dispersal. However, you should bear in mind that the fan noise increases the higher you set the speed. It’s also equipped with a night light if you like to leave the light on while you sleep. You can also set its auto-off timer to shut itself down, so you don’t have to. When it’s time to replace your air filter, the replace filter indicator lets you know. 


  • Aroma slot for fragrant air
  • 5-in-1 filtration system
  • 360-degree protection
  • Customizable control
  • Lightweight and durable


  • The HEPA-type filter is not the very best
  • The fan is noisy when the unit is set to high speed

PURO²XYGEN P500 – Hepa Air Purifier

The PURO²XYGEN P500 Hepa Air Purifier is a genuinely sophisticated gadget. It has almost no fundamental flaws, making it perfect for any household and application. Seriously, this unit boasts all the bells and whistles that you’d expect from a very high-end air purifier, including some that are innovative and thoughtful. Apart from this, this air purifier practically takes care of itself, and it’s so low maintenance. If you’re looking for an air purifier that offers complete peace of mind, this is it. 

The first thing you’ll notice is the sleek and elegant design of this unit. If you’re particular about home decor, it’s safe to say that this air purifier will do nothing to detract from the beauty of any space it occupies. Speaking of which, it does have a relatively large footprint, so you might need to take that into account. It comes with remote control, so you can more accurately interpret its functions and operate it from across the room. For such an impressively sophisticated-looking machine, however, it is effortless to use. It doesn’t take a lot of effort to get this machine up and running. 

As we mentioned earlier, this air purifier is packed full of cool features, and one of the most impressive is the air quality indicator. This setting automatically assesses air quality in your home once you turn on the machine and immediately get to work filtering your air. 

It also boasts a six-stage advanced purification system that’s pretty effective. Again, unlike most other air purifier units, this one is equipped with a True HEPA filter. This means that it, along with a mesh pre-filter, activated carbon filter, cold catalyst filter, UV light sanitizer, and ionizer, can eliminate up to 99.98% of airborne contaminants including mold spores in any space. 

This unit offers three-speed modes. It gets louder the higher you set the speed, although it starts pretty quiet. It also offers a child lock setting, led night light, filter health indicator, sleep timer, and a beneficial auto mode. Our only peeve with this air purifier is that it doesn’t cover large spaces very well. 


  • 6-Stage Advanced Purification System
  • True HEPA filter
  • Child Lock
  • Air Quality and Filter Health Indication
  • Auto Mode


  • It doesn’t handle large spaces very well
  • Is considerably large

ENVION Ionic Pro Platinum Negative Ion Air Purifier

This air purifier was designed with convenience and ease of operation in mind, and it delivers on both counts. Being an Ionizer, it also requires minimal maintenance, is very energy-effective, and pretty quiet compared to other units. Also, since you wouldn’t even need to change the air filter, it’s a more budget-friendly option. Quite simply, it does what you’ll expect for a gadget with its price tag, with a few extra features thrown in. 

This Ionizer sports a sleek, matte black finish. It’s not exactly small, although it is pretty compact and not too heavy. Its most attractive features are:

  • Its LED indicator.
  • A sleep timer that’s programmable for up to 24 hours.
  • A control panel light dimmer.
  • A silent mode setting.
  • Controls for fan speed.

Pretty basic, but this design helps with ease of operation, so we can’t complain too much. 

This unit can effectively remove 99.9% of airborne allergens and other contaminants in a room. It works best in medium-sized rooms and can be pretty quickly moved around. While it’s not exactly silent, it is pretty quiet and will not disrupt your sleep too badly, even at the lowest settings. Remember, the higher you set the speed, the noisier it gets. 


  • Easy to operate
  • Relatively quiet operation
  • Energy efficient
  • You don’t ever have to change air filters
  • Budget-friendly


  • Very basic
  • Not very durable

What To Look Out For When Selecting A Negative Ion Generator

It’s not a very straightforward task finding the perfect negative ion generator for you that will remove harmful positive ions. There are several options available in the market, and trying to decide which one to get can be confusing. 

However, by looking out for the following features, you’ll be sure to find one that’ll satisfy you completely:


The first thing to consider is the layout and design of your preferred unit. You’d have to decide whether you want a large one that you can stash somewhere in your living room or a small, compact one that you can carry around with you. 


Ideally, opt for a negative ion generator that offers convenient operation modes. Several units these days offer variable speed modes and sleep timer modes. These settings will help you manage your energy consumption more efficiently. 

Noise Level

Noise is the one thing that you don’t need from your negative ion generator. Noisy units can frustrate and make it impossible for you to sleep at night, so you should be careful with this. 

However, most negative ion generators, and those without fans, in particular, are pretty noiseless. 

Coverage Area

Before settling for a negative ion generator, make sure you compare its coverage area with the size of the room where you intend to use it. An I that’s unable to cover the entire room will probably defeat the whole purpose. 


As a general rule, the more negative ions a unit can emit, the better the air quality you get with reduced airborne particles. You should check the efficiency of an Ionizer before you opt for it and see what particle count per ML you end up with. 

Final Words

There’s no doubt about it; negative ion generators can undoubtedly sanitize the quality of your health, and by extension, your life. They offer several advantages, each of these geared towards helping you live a little healthier and sleep a bit better. 

It would be the easiest thing to walk into a store and ask for the best negative ion generator on sale. But, while several products claim that tag, only a few deliver on that promise. 

We’ve done all the research for you and come up with this list of the finest products in the market. We’ve also included the lowdown on all the best features to look out for in a negative ion generator, in case you’re planning to walk the aisles yourself.
