Design and build quality

With the same dimension as Winix U450, Winix P450 air cleaner is certainly not small in every aspect, with the width of 48 cm, the height of 65 cm and depth of 30 cm, placing Winix P450 in a compact space might be an issue for some.

Overall the quality of this Korea built air purifier is solid with no off-gassing in any way.

Practicality, build quality, durability is up next on just what we will pay attention to. Winix P450 interest in fitting is detectable, the framework used mixed materials that is well installed with no apparent gap. The base feels solid on the ground without any sort of jiggling movement. Despite the confined air ventilation on the air purifier, the air purifier capacity is rather sufficient for standard purifying without having to nearly always checking on the air purifier. The nice handles are positioned right above the air purifier. You can swiftly make changes to the setting. When needed, clean the air purifier with a damp rag to do away dust. Utilized mild laundry soap on recurring smeared.

Applicable area and airflow

With Winix standard 3-stage cleaning system, any forms of pollutants will be absorbed first through the carbon pre-filter, subsequently filter through a tight HEPA filter and finally, the remaining particles will be break apart and release for the next round of filtering. With the continuously repeating process, Winix P450 can delivery from 83.2 m³/h of airflow in low speed setting all the way up to 483 m³/h in high-speed setting. With all of the features above, Winix P 450 can cover up to 42 m2 (452 ft2) of the applicable area; perfect for medium-size living room or bedroom. When put next with other fairly equivalent segment air purifiers, Winix P450 purifying applicable radius is moderate.

Filters and filtration

Similar to all FresHome series air purifier combination filter that is able to clean and eradicate contaminants rapidly. The 113250 / Size 25 One-Year Replacement Filter Set (bundled) pre-filter would absorb large air pollutants and prolong the HEPA filter lifespan. 113250 / Size 25 One-Year Replacement Filter Set (bundled) HEPA filter will effectively catch and hinder terrible home particles from steady flowing out in the air. The high grade 113250 / Size 25 One-Year Replacement Filter Set (bundled) carbon filter will take up notorious odors come from paint, detergents, VOC and cigarette smoke. The PlasmaWave spread ions and electrostatically-charged air-borne contaminants before releasing clean air back to the air. In short, any type of dangerous contaminants such as dust, mold, mildew, dust mite, pollen, and pet dander will be a draw and wipe off.

Noise level and power consumption

Winix FresHome P450 noise level is kept at a low-level thanks to the precisely built motor. With minimal noise generated, the air purifier will have absolutely zero impact on user’s day to day life. For the record, the air purifier noise level is still tremendously quiet put next with same collection home appliances. Staying with the power input, Winix FresHome P450 power consumption is surprisingly low too at 11 | 110 watts given its air circulation efficiency. You will save an abundance of money on electrical bills in long-run. Like other equally low voltage home appliances within the type, the air purifier still has low to acceptable power input.

Final thoughts on Winix P450

Let’s talk about the pricing first, it is priced below Winix U450 (Winix top of the line signature series) although not by a far margin. If you compare the spec between the two, you will find that Winix P450 is rather similar to Winix U450 except for a slightly weaker airflow delivery, 2 years less warranty and 2-stage lesser filtration. There is also complains from other parties on the lack of the ability to turn off the ionizer features which sadly I have to agree to. Put aside all that, Winix P450 is essentially a good, well-balanced air purifier that will unquestionably improve your indoor air quality.
