NuWave Air Purifiers: Washable Filters or HEPA?

NuWave is best known in kitchens for countertop cookers, but the brand also sells a family of home air purifiers, and its big idea in this category is simple: a filter you wash instead of a filter you keep buying. If you have never owned an air purifier, that single choice, washable versus replaceable, shapes most of what living with one feels like, so this guide explains it in plain words before pointing you to a model.
The six NuWave air purifiers below split into three groups: the Forever models built around a never-replace, washable filter system, the OxyPure ZERO and Zero Plus towers with reusable filters for bigger rooms, and the small OxyPure HEPA unit for a bedroom, with one app-controlled Oxypure Zero in between.

A quick note on how we built this table: we compared the Amazon listings, their titles and the specifications NuWave supplies, not our own lab measurements. Where a listing is silent, we say so rather than guess, and several of these listings are quite short.
Nuwave Forever Smart Air Purifier for Buyers Who Hate Filter Refills

Nuwave Forever Smart Air Purifier
Best for: Buyers who never want to buy filters
Pros
- Never-replace filter system
- Smart model per listing
- Mid-size footprint
Cons
- Coverage area not listed
- Heavy at about 22 pounds
The Nuwave Forever Smart Air Purifier is sold on one promise that sits right in its listing title: a “Never Replace Air Filter System.” In everyday terms, that means the filter is designed to be cleaned and put back rather than thrown away and bought again. For a first-time owner, this removes the most common surprise of air purifier ownership, which is discovering months later that the unit needs a new filter cartridge.
The listing gives its size as 13 x 14.25 x 22.81 inches and its weight as 21.85 pounds, so this is a floor-standing unit roughly the height of a small side table, not something you tuck onto a nightstand. The word “Smart” appears in the name, but the listing we compared does not specify which smart features are included, how it connects, or how large a room it is meant for. If app control or a stated coverage figure matters to you, check the product page carefully before buying.
This model suits someone who wants to set up a purifier in a living room or home office and stop thinking about filter orders. If you need a published room-size rating to match your space, the Zero Plus further down is the only large model in this list with one.

Nuwave Forever Plus Air Purifier
Best for: Large rooms with washable-filter upkeep
Pros
- Washable filters
- Largest cabinet in the Forever line
Cons
- Heaviest at 28.6 pounds
- Room size not listed
The Nuwave Forever Plus Air Purifier is the bigger sibling in the Forever family. Its listing title calls out “Washable Filters,” which again means the filters are meant to be rinsed or cleaned and reused. At 14.19 x 14.19 x 26.25 inches and 28.6 pounds, it is taller and heavier than the Forever Smart, and it shares its weight with the Zero Plus as the heaviest units in this roundup.
A larger cabinet usually leaves room for more filter surface and a bigger fan, which is why shoppers tend to look at models like this for open living areas. However, the listing does not specify a room coverage figure, fan speeds or smart features, so we cannot confirm how it compares on paper with the Zero Plus. Treat the size as a hint, not a promise.
Pick the Forever Plus if you like the washable idea and want a sturdier, larger unit that will mostly stay in one spot. If you plan to move your purifier between rooms often, its weight makes the lighter Oxypure Zero or the tiny OxyPure HEPA a friendlier choice.
Nuwave OxyPure HEPA Air Purifier for Bedrooms
Nuwave
Nuwave OxyPure HEPA Air Purifier for Home Bedroom up to 857 Sq Ft

Nuwave OxyPure HEPA Air Purifier
Best for: Bedrooms and small spaces
Pros
- HEPA filter
- Rated up to 857 sq ft
- Light at 3.5 pounds
Cons
- Filter replacement schedule not listed
The Nuwave OxyPure HEPA Air Purifier is the odd one out, and in a good way for small spaces. It is the only model here with “HEPA” in its listing title, and it is by far the smallest: 7.6 x 7.6 x 16.8 inches and just 3.5 pounds. Its title says it is meant for a home or bedroom and gives coverage of up to 857 square feet.
HEPA is a filter standard, and in general terms a HEPA filter is a dense pleated sheet that traps very fine dust and particles as air is pushed through it. The trade-off most first-time buyers learn about later is that HEPA sheets are normally replaced rather than washed. The listing does not specify how often this model’s filter should be changed or whether it can be cleaned, so ask that question before you buy if running costs matter.
This is the easiest pick for a gift, a dorm room or a bedroom where a big tower would feel out of place. It gives way to the Forever or ZERO models if you would rather avoid replacement filters, and to the Zero Plus if your space is much larger than a bedroom. If you want to see how a truly desk-sized option compares, our guide to a wearable personal air purifier covers the very smallest end of the category.
Nuwave OxyPure ZERO Air Purifier with Reusable Bio Guard Filters
Best for: Tech fans wanting app control
Pros
- App control
- 6 fan speeds
- Built-in timer
Cons
- Room size not listed
- Filter type not in title
Best for: Open-plan homes and very large rooms
Pros
- Covers up to 3,210 sq ft
- Biggest capacity in this list
Cons
- 6 pounds, bulky cabinet
- Filter type not detailed
Nuwave
Nuwave OxyPure ZERO Air Purifier with Washable & Reusable Bio Guard Filters
Price and specifications are read from the Amazon product page and can change.
Nuwave OxyPure ZERO Air Purifier
Best for: Families wanting reusable Bio Guard filters
Pros
- Washable, reusable Bio Guard filters
- Floor-standing tower size
Cons
- 22 pounds to move
- Coverage area not listed
The Nuwave OxyPure ZERO Air Purifier is the model that put NuWave’s washable approach on the map. Its listing title names “Washable & Reusable Bio Guard Filters,” so Bio Guard is the brand’s name for the filter set inside. The listing we compared does not describe the layers of that filter in detail, so we will not guess at what each one does.
It measures 12 x 14 x 23 inches and weighs 22 pounds, placing it in the same size bracket as the Forever Smart. Coverage area, fan speeds and controls are not specified in the data we have. One thing to watch: there is a second product in this list sold as the “Oxypure Zero” with a different model number and a much smaller body, so compare model numbers (47251 for this one) when you shop.
Choose this model if the reusable Bio Guard filter is the feature you want and you have a medium to large room. If you need an exact room rating, the Zero Plus is the better documented option. Pet owners comparing reusable filters with other approaches may also find our look at an air purifier aimed at pet hair useful.
Nuwave OxyPure Zero Plus Air Purifier for Very Large Rooms
The Nuwave OxyPure Zero Plus Air Purifier is the capacity leader of this lineup. Its listing title states that it covers up to 3,210 square feet and calls it a large-room model, which is several times the figure given for the OxyPure HEPA.
That capacity comes in a large body: 14.25 x 14.25 x 26.25 inches and 28.6 pounds. The title does not state the filter type, so while the name places it in the ZERO family, we cannot confirm from this listing alone that it uses the same washable filters. Fan speeds, timer and app features are also not specified.
This is the pick for open-plan homes, basements, large family rooms or anyone who wants one machine working hard in a big shared space. For a single bedroom it is more machine than you need, and the OxyPure HEPA or the compact Oxypure Zero will be easier to live with.
Nuwave Oxypure Zero Air Purifier for App Control and Fine-Tuning
The Nuwave Oxypure Zero Air Purifier is the model with the most features named in its title: six fan speeds, a timer and app control. Six speeds let you run it quietly at night and turn it up after cooking or cleaning, and a timer lets it shut off on its own. App control means you can adjust it from your phone, although the listing does not specify which app or what Wi-Fi setup is needed.
At 9.5 x 11 x 18.5 inches and 13.2 pounds, it sits between the tiny HEPA unit and the big towers, which makes it realistic to carry from a bedroom to a living room. Room coverage and filter type are not listed in the data we compared, so check those details on the product page.
Pick this one if you are the kind of buyer who likes to control things from a phone, or if you are giving it as a gift to someone who enjoys gadgets. If the washable-filter promise is your main reason for buying NuWave, the Forever and ZERO models state it more clearly.
How to Choose the Right NuWave Air Purifier
Start with the filter question. A washable filter, as named on the Forever Smart, Forever Plus and OxyPure ZERO, is cleaned and reused, so upkeep is a few minutes of rinsing rather than a recurring order. A HEPA filter, as on the OxyPure HEPA, is a proven way to trap fine particles, but it is usually replaced over time. Neither choice is wrong; it depends on whether you prefer chores or refill orders.
Match the room size. Only two listings give a figure: up to 857 square feet for the OxyPure HEPA and up to 3,210 square feet for the Zero Plus. For the others, use cabinet size as a rough guide and look for a coverage rating on the product page before deciding.
Think about moving it. The towers weigh between about 22 and 28.6 pounds, which is fine for a unit that stays put. If you want to carry it from room to room, the 13.2-pound Oxypure Zero or the 3.5-pound OxyPure HEPA are much easier.
Decide how much control you want. The Oxypure Zero is the only model here whose listing names app control, six fan speeds and a timer. If you just want to switch it on and forget it, any of the others will do.

FAQ
Which NuWave air purifier should I buy for a bedroom?
The OxyPure HEPA is the natural fit. It is the smallest and lightest model here and its listing states coverage up to 857 square feet, which comfortably includes a typical bedroom.
What is the difference between the OxyPure ZERO and the Zero Plus?
The OxyPure ZERO lists washable, reusable Bio Guard filters and weighs 22 pounds. The Zero Plus is a larger 28.6-pound unit whose listing highlights coverage up to 3,210 square feet but does not describe its filter type.
Do NuWave washable filters really never need replacing?
The Forever Smart listing describes a “Never Replace Air Filter System,” and the Forever Plus and OxyPure ZERO list washable filters. The listings we compared do not explain the cleaning schedule or the lifespan in detail, so follow the manual that ships with your unit.
Why are there two OxyPure Zero models?
NuWave sells more than one product under similar names. In this list, model 47251 is the 22-pound OxyPure ZERO with Bio Guard filters, while model 47361 is the 13.2-pound Oxypure Zero with six fan speeds, a timer and app control. Check the model number on the listing.
Which NuWave air purifier has app control?
Among these six, only the Oxypure Zero model 47361 lists app control. The Forever Smart has “Smart” in its name, but its listing does not specify its smart features.
Is HEPA better than a washable filter?
They solve the same job in different ways. HEPA is a well-known standard for catching fine particles and is usually replaced, while washable filters trade refill costs for regular cleaning. Pick the upkeep style that suits your routine.
