The HomeZens earCandle Air Purifier stands out with its sleek 7-inch plug-in design, making it a perfect fit for various rooms in your home. Simply plug it into a standard 120V outlet, adjust the angle to your preference, and let it work its magic. 

The device lives up to its promise, utilizing UV-C light to effectively sanitize the air, eliminating up to 99.9% of germs and bacteria without the need for chemicals.

While the HomeZens earCandle Air Purifier excels in many areas, it’s important to consider its limitations. Due to its compact size, it may not be suitable for whole-room air cleaning. 

However, it proves to be a reliable companion for smaller spaces like kitchens, bathrooms, and children’s rooms, where it delivers noticeable improvements in air quality.

One noteworthy drawback is the polarized plug design, which limits outlet availability and may interfere with other plugs. It’s a minor inconvenience that could be addressed with a 180-degree rotatable plug for enhanced flexibility. 

Additionally, although the unit can be mounted sideways, it might not be ideal for certain settings.

Compared to previous models, the HomeZens earCandle Air Purifier showcases advancements in both performance and design. It effectively eliminates moldy odors and improves overall air quality. 

However, sensitive individuals might experience slight irritation, and the source of this irritation, whether it’s ozone or other air compounds, remains unclear.

The UV-C light technology, combined with its compact size and ease of use, make it a top choice for those seeking reliable air purification.

During our evaluation, we discovered a misconception regarding the device’s plug rotation. While some might expect a full 180-degree swivel, the polarized plug actually only rotates 90 degrees. So, be mindful of the range of receptacle choices you have when using this air purifier.

We also encountered a few instances where the fans became excessively noisy after extended use. Though it’s important to note that this occurred in only three out of twelve units we tested. HomeZens could address this issue to ensure consistent noise levels and a pleasant user experience.

We personally tested and used the Clarifion DSTx air purifier, and we’re here to share our experiences, research, and analysis with you. So sit back, relax, and let’s dive into the world of cleaner, fresher air!

One of the standout features of the Clarifion DSTx is its combination of a negative ionizer and a HEPA filter. This powerful duo works together to tackle airborne pollutants, such as dust, smoke, pet dander, and odors, ensuring that the air you breathe is as pure as possible. 

We found that placing the device near windows and doors further enhanced its performance, as it effectively reduced these pollutants.

One interesting benefit we discovered is that the negative ions emitted by the DSTx have a unique ability to attract dust and allergens, causing them to settle on the ground. 

This resulted in a significant reduction in floating dust particles and less dust on furniture. Who wouldn’t love to spend less time dusting and more time enjoying their clean space?

Now, let’s talk about the price tag. The Clarifion DSTx is not the most budget-friendly option out there, but trust us when we say the long-term benefits make it worth the investment. 

The effectiveness of this air purifier in reducing dust and improving air quality is impressive, and that’s backed by positive user reviews. 

Many users have experienced success in reducing dust on specific furniture pieces, which is a clear sign of its effectiveness.

The Clarifion DSTx offers two fan speed settings: low and high. While the low setting is quiet, it may not be as powerful as some users desire. 

On the other hand, the high setting provides more power but comes with increased noise levels. Some users have expressed a desire for a medium speed option that balances power and noise. We understand the importance of finding that sweet spot for personalized comfort.

Compared to its competitors, the Clarifion DSTx stands out with its performance. It effectively neutralizes odors and maintains clean air, making it a great choice for households with children. 

The emitted light is not overly bright, and the device’s size is suitable for smaller spaces like bathrooms. However, for larger rooms, it might be necessary to use multiple units for optimal coverage.

If you’re dealing with persistent cigarette smells, the Clarifion DSTx can come to the rescue. When used on the high setting for extended periods, it noticeably dissipates the odor. 

However, it’s worth noting that the smell tends to return quickly once the purifier is turned off. So, for continuous relief, keeping it plugged in is key.

Allergy sufferers will be glad to hear that the Clarifion DSTx has provided relief to users with dust allergies, especially in carpeted bedrooms. The device effectively clears dust and dander from the air, creating a fresher and more comfortable environment.

Let’s talk about noise levels. We found that the Clarifion DSTx’s noise varies depending on the selected setting, with higher settings being louder.

However, we expect the device to perform similarly on lower settings, which produce less noise. So if you’re sensitive to noise or prefer a quieter atmosphere, you can still enjoy the benefits of this air purifier on the lower settings.

In summary, the Clarifion DSTx has proven to be a helpful solution for improving air quality and reducing odors in various rooms. It effectively combats dust, smoke, pet dander, and odors, providing a fresher and cleaner environment.

While the noise level on higher settings can be a bit loud, the lower settings are likely to provide satisfactory results for those seeking a quieter experience.

Additionally, we discovered conflicting information regarding the unit’s coverage area, with some sources stating 50 square feet while others claim 325 square feet. This ambiguity can make it challenging to determine the perfect fit for your specific needs.

Another point worth mentioning is the use of ozone in this air purifier. While ozone emission can have positive effects, such as the disappearance of mice reported by one user, caution is advised due to its potential adverse effects on birds. 

It’s essential to consider your environment and any potential sensitivities before opting for an ozone-emitting air purifier. 

Additionally, some users experienced an audible sound even when the dial was turned off, and the lack of grip on the dial and absence of an indicator light to show the dial’s position were slight inconveniences.

We also came across a few isolated cases where two units needed replacement due to issues with turning on and excessive vibration. While these incidents were not widespread, it’s worth keeping in mind. 

Furthermore, we found that while the pureAir 50 effectively keeps odors at bay, it may not be as efficient in reducing dust particles. If you’re primarily looking for a solution to tackle dust allergies, you might want to explore other options.

In conclusion, the Greentech Environmental pureAir 50 air purifier offers a blend of impressive features and some minor caveats. Its ability to effectively eliminate odors and create a fresh environment is a standout benefit. 

The addition of Wi-Fi compatibility and scheduling options further enhances its usability and convenience. However, it’s crucial to consider potential concerns about ozone emission and to assess its long-term effects on health.

Technological Differences Between Plug-in Purifiers and Standard Air Purifiers

When it comes to choosing an air purifier, you may come across different types, including plug-in purifiers and standard air purifiers. Understanding the technological differences between these two options can help you make an informed decision and select the most suitable device for your needs. 

Plug-in Purifiers:

Plug-in purifiers are compact and portable devices designed to be plugged directly into electrical outlets. They are commonly used in smaller spaces like bedrooms, offices, or bathrooms. 

Unlike standard air purifiers, plug-in purifiers are usually single-function devices specifically designed to address certain pollutants or odors.

Filtration Technology:

Plug-in purifiers typically utilize a combination of technologies to improve air quality. Some common methods include:

a) Carbon Filters: These filters employ activated carbon to trap and remove odors, smoke, and volatile organic compounds (VOCs) from the air.

b) Ionic Technology: Ionic purifiers release negative ions that bind to positively charged particles such as dust and allergens, causing them to fall out of the air.

c) UV-C Light: Some plug-in purifiers incorporate UV-C (ultraviolet-C) light technology to kill bacteria, viruses, and mold spores.

Coverage Area and Effectiveness:

Due to their smaller size and limited filtration capacity, plug-in purifiers are suitable for small rooms or specific areas within a larger space. They are not intended for whole-house or comprehensive air purification.

Standard Air Purifiers:

Standard air purifiers, also known as room air purifiers or whole-house air purifiers, are larger devices designed to purify the air in larger spaces or even entire homes. 

They offer more comprehensive air purification capabilities and are suitable for addressing a wider range of pollutants.

Multiple Filtration Stages:

Standard air purifiers often incorporate multiple filtration stages, including pre-filters, HEPA (High-Efficiency Particulate Air) filters, activated carbon filters, and sometimes additional specialized filters. 

These stages work together to capture and remove various contaminants such as dust, pollen, pet dander, mold spores, bacteria, and more.

CADR and ACH Ratings:

Standard air purifiers are evaluated based on their Clean Air Delivery Rate (CADR) and Air Changes per Hour (ACH). 

CADR measures the volume of clean air a purifier can deliver per minute, while ACH indicates how many times an air purifier can filter the entire volume of air in a room within an hour. These ratings help determine the efficiency and effectiveness of a standard air purifier.

Smart Features and Connectivity:

Many standard air purifiers come with advanced features like built-in sensors to monitor air quality, automatic mode adjustment, and connectivity options to control the device remotely via mobile apps or voice assistants. 

These features enhance convenience and allow for more precise control over the purification process.

Benefits Of Owning A Plug-In Air Purifier

Now, we will explore the numerous advantages of owning a plug-in air purifier.

Targeted Air Purification:

Plug-in air purifiers are designed to address specific pollutants or odors in localized areas. 

Whether it’s pet dander, cooking smells, tobacco smoke, or volatile organic compounds (VOCs), these devices can effectively target and remove these contaminants, providing you with cleaner and fresher air.

Compact and Portable:

One significant advantage of plug-in air purifiers is their small size and portability. They can be easily moved from one room to another or even taken along while traveling. 

This feature makes them ideal for smaller spaces like bedrooms, bathrooms, offices, or hotel rooms, where you need immediate air purification without the hassle of bulky equipment.

Easy Installation and Use:

Plug-in air purifiers are incredibly easy to install and use. Simply plug them into an electrical outlet, and they start working immediately. 

There are no complex installation processes or adjustments required. Many plug-in purifiers also have user-friendly controls, allowing you to adjust settings or choose different modes according to your preferences.

Energy Efficiency:

Compared to larger standard air purifiers, plug-in purifiers are typically more energy-efficient. Their compact size and focused air purification make them consume less power while still effectively improving the air quality in smaller spaces. 

This energy efficiency not only helps reduce electricity costs but also minimizes the environmental impact.

Low Maintenance:

Plug-in air purifiers often require minimal maintenance. Most models use replaceable filters or filter cartridges that need periodic changing, usually every few months. 

Filter replacement is a simple and quick process, and many devices come with indicator lights or reminders to let you know when it’s time for a filter change. 

Additionally, some plug-in purifiers have washable filters that can be easily cleaned, eliminating the need for frequent replacements.


In terms of affordability, plug-in air purifiers are generally more budget-friendly than larger, comprehensive air purification systems. They offer a cost-effective solution for addressing specific air quality concerns without investing in a larger unit. 

The initial purchase cost is often lower, and ongoing maintenance expenses are typically minimal.


Plug-in air purifiers come in a variety of types and models, each catering to specific air purification needs. Whether you require an odor eliminator, an allergen reducer, or a mold spore remover, you can find a plug-in purifier tailored to your requirements. 

This versatility allows you to choose a device that best matches the specific air quality challenges you face.
