Frequently Asked Questions

Common questions about this comparison

Which air purifier is better for a larger living room?

The Coway AP-1512HH is superior for larger rooms, covering 375 sq ft effectively. The Shark HC451 is only suitable for small spaces up to 104 sq ft, ideal for a bedroom or personal office where multifunctionality is key.

What's the main difference in air purification power between the two?

The Coway AP-1512HH has a significantly higher CADR Smoke of 240, compared to Shark HC451's 66.67. This means the Coway cleans air much faster and in larger areas (375 sq ft vs. 104.17 sq ft).

Is the Coway's higher price ($219.99 vs $199.99) justified?

Yes, if your priority is pure air purification for larger spaces. The Coway offers vastly superior CADR (240 vs 66.67) and coverage (375 sq ft vs 104.17 sq ft) for just a $20 difference, making it a better value for air cleaning performance.

Which product offers more features beyond air purification?

The Shark HC451 provides more features, functioning as a 3-in-1 device that purifies air, heats, and provides fan cooling. The Coway AP-1512HH is solely a dedicated air purifier, focusing on comprehensive air cleaning.
