A good air purifier is a great tool to use for dealing with the various allergens, dust, pet dander, and even mold that sometimes build up in the home.
The Holmes HAP242-NUC Desktop Air Purifier is an excellent air purifier for filtering the air in smaller rooms, but you might need a more powerful model for larger spaces. This air purifier is such a great deal that it has shown up on several of our lists and was even our top selection for mold.
Key Point: Holmes Air Purifier Review, we explore the major selling points of this air purifier. The most notable of which is its seriously alluring price tag, which allows your to pick one up for under $50.
The Holmes company has been around since the early 1980s and was at one time a subsidiary of Berkshire Partners (which shouldn’t be confused with Berkshire Hathaway).
The Massachusetts-based company produces several different products including fans, humidifiers, and of course numerous air purifiers.
Holmes HAP242-NUC Desktop Air Purifier
Most people don’t realize it, but indoor air quality can often be worse than outdoor air quality.
The HAP242-NUC Desktop Air Purifier is an entry level air purifier that is compact and relatively lightweight. It is also exceptionally inexpensive, coming in at around $40.
This device features a two-stage filtration process including a HEPA-type filter that can effectively remove most fine particulates from the air. The filter that comes with the machine has also been enhanced with Arm & Hammer baking soda to help remove odors.
If you are not comfortable with the fact that this device only comes with a HEPA-type filter rather than a True HEPA filter, you can customize your device with different filters. There are four different filters to choose from, including two that are true HEPA filters, ensuring even better filtration.
The replacement filters run between $10 and $20, depending on which model you choose.
There is also a charcoal filter. Charcoal — or activated carbon — is great for capturing gases because it can bond with them through the process of adsorption.
The device does not come with a sensor to tell you when to change out the filters, but the general rule of thumb for a HEPA filter is between 12 and 18 months.
The HAP242-NUC also features an optional ionizer, which sends negative charges into the air to bond with particles, making them too heavy to remain in the air. Then, the particles fall to the ground where they can be easily vacuumed.
However, you should be very careful not to use the ionizer too often, as ionizers have been known to produce trace amounts of ozone, a gas that can be very dangerous if inhaled in large quantities.
Coverage and Noise
The Holmes HAP242-NUC is not built to cover large rooms. The recommended space is around 110 square feet, making it ideal for an office, dorm room, bedroom, or small classroom.
The machine uses a fan to draw air in through the front and into the filters, and then back out through the top. The fan can be operated at three speeds. The highest speed can be quite loud, while the lowest speed sounds like a quiet fan.
Most consumers prefer the middle speed because it provides good filtration and the noise level is relatively low.
One of the great features of the Holmes HPA242-NUC is its size. It is designed as a table top air purifier, but it can be placed vertically or horizontally depending on your needs.
This model is available in either white or black, and the rounded edges in the design also make it child-friendly.
Holmes also offers a three-year limited warranty.
Pros and Cons of the Holmes Air Purifier HAP242-NUC
