บางครั้งการเลือกซื้อเครื่องฟอกอากาศสักเครื่องก็เป็นเรื่องที่ยุ่งยาก โดยเฉพาะการหาซื้อครั้งแรก เพราะคุณไม่รู้อะไรเลยนอกจากความต้องการที่จะมีอากาศสะอาดไว้หายใจ เครื่องฟอกอากาศนั้นมีด้วยกันหลายราคา มีตั้งแต่ตัวท็อปที่มีราคาแพงมาก สามารถทำงานได้หลากหลาย สามารถเชื่อมต่อกับเครื่องใช้ไฟฟ้าอื่น ๆ ผ่านสัญญาณอินเตอร์เน็ตภายในบ้านได้ ไปจนถึงเครื่องที่ธรรมดา ราคาสมเหตุสมผล ที่มีจุดประสงค์หลักคือฟอกอากาศและดักจับฝุ่น PM2.5 ถึง PM10 ยกตัวอย่างเช่น AirCleaner Personal ของเรานั่นเอง
Buying an air purifier can be very confusing, especially if it’s your first time and the only thing you know is that you want clean
Current and voltage are probably the most important electrical properties in any electrical circuit. They are the cornerstones of every other parameter and the first
