Quick Summary
The AlorAir PureAiro HEPA Pro 870 is a commercial-grade air scrubber designed for renovation, restoration, workshops, basements, crawl spaces, and other environments where airborne dust, particles, odors, and contaminants can become a problem.
It combines a MERV 10 pre-filter, True HEPA filtration, activated carbon, and built-in UV-C light, with variable airflow up to 550 CFM. It is more powerful and specialized than a typical household air purifier, making it better suited to demanding indoor-air applications.
Overview
The PureAiro HEPA Pro 870 is positioned as a portable industrial and commercial air scrubber rather than a standard bedroom or living-room purifier.
Its main purpose is to move relatively large volumes of air through several filtration stages, helping reduce airborne particles and odors during jobs such as renovation, water-damage restoration, cleaning, construction, and mold-remediation work.
AlorAir also lists applications including garages, warehouses, basements, offices, laboratories, clinics, shops, restaurants, and other enclosed spaces.

Three-Stage Filtration
One of the strongest features of the PureAiro HEPA Pro 870 is its multi-stage filtration system.
MERV 10 Pre-Filter
The first stage captures larger airborne material before it reaches the main HEPA filter.
This helps reduce dust loading on the finer filtration media and can extend the useful service life of the main filter.
True HEPA Filter
The HEPA stage is designed to capture fine airborne particles and is the core reason this unit fits SiftNfilt’s Air Filtering category.
For environments affected by construction dust, restoration debris, pollen, pet dander, and other suspended particles, HEPA filtration provides a more robust approach than basic fan-and-filter systems.
Activated Carbon
Activated carbon adds an odor and gaseous-pollutant filtration layer.
This is particularly useful in environments affected by smoke, renovation smells, pets, or other indoor odors. AlorAir
UV-C Light
The unit also includes built-in UV-C light technology.
According to AlorAir, the UV-C system operates alongside the filtration stages and is intended to help address airborne microorganisms while air passes through the unit. AlorAir
It is important to treat UV-C as an additional feature rather than a replacement for HEPA filtration. The core filtration performance still comes from the physical filtration stages.
Airflow and Performance
The PureAiro HEPA Pro 870 provides variable airflow from approximately 270 to 550 CFM.
That level of airflow makes it suitable for larger or more demanding spaces than many small household air purifiers.
Variable-speed control is useful because it allows the operator to balance:
- Air-cleaning speed
- Noise
- Power consumption
- Room size
- Work conditions
At maximum output, the unit is designed to process substantial volumes of air quickly.
Build Quality
The HEPA Pro 870 uses a rotomolded polyethylene housing, a construction style commonly used in commercial equipment because it is resistant to impact and repeated transport.
The unit is also:
- Stackable
- Portable
- Ductable
- Equipped with a filter-change indicator
- Fitted with a circuit breaker
- Designed with a maintenance-free bearing motor
These features make it more suitable for job-site use than a conventional consumer air purifier.
Daisy-Chain Capability
A useful commercial feature is the ability to daisy-chain up to three units from one power outlet, according to AlorAir.
For contractors or larger restoration jobs, this makes it easier to operate multiple air scrubbers without requiring separate outlets for every unit.
Noise Level
he published sound-pressure level is approximately 65 dBA.
That is noticeably louder than many bedroom-focused air purifiers, which is expected given the unit’s airflow and commercial positioning.
For a living room or bedroom, noise may be a drawback. For renovation, restoration, workshop, or commercial use, it is more likely to be considered acceptable.
Where It Makes the Most Sense
The PureAiro HEPA Pro 870 is best suited to environments such as:
- Construction and renovation
- Water-damage restoration
- Basements and crawl spaces
- Garages and workshops
- Warehouses
- Commercial spaces
- Offices
- Clinics and laboratories
- Smoke-affected rooms
- Dust-heavy environments
It can also be used in residential spaces, but its industrial form factor means it is probably excessive for someone who simply wants a quiet purifier for a small bedroom.
Pros & Cons

- True HEPA filtration
- Activated carbon filtration
- MERV 10 pre-filter
- Built-in UV-C
- Up to 550 CFM airflow
- Variable speed control
- Commercial-grade housing
- Stackable design
- Daisy-chain capability
- Filter-change indicator
- Long 23-foot power cord

- Replacement filters add ongoing cost
- 115V / 60Hz specification makes it primarily suited to the US market
How Is It Different from a Household Air Purifier?
The biggest difference is purpose.
A conventional home air purifier is usually optimized for:
- Bedrooms
- Living rooms
- Quiet operation
- Continuous daily use
- Consumer-friendly appearance
The PureAiro HEPA Pro 870 is optimized more for:
- High airflow
- Job-site durability
- Dust-heavy environments
- Restoration
- Construction
- Odor control
- Commercial use
So while both filter air, they are built for different operating environments.

Final Verdict
The AlorAir PureAiro HEPA Pro 870 is a strong fit for users who need more than a standard household air purifier.
Its combination of True HEPA, activated carbon, MERV 10 pre-filtration, UV-C, variable airflow, and commercial-grade construction makes it particularly suitable for restoration, renovation, workshops, basements, crawl spaces, and other demanding environments.
For SiftNfilt, it also adds useful variety to the Air Filtering section because it covers a very different use case from a conventional residential purifier.
Its main limitations are size, noise, weight, and the fact that it is clearly oriented toward the US 115V market.
